An astronaut and his space suit have a combined mass of 157 kg. The
astronaut is using a 5 kg tqol kit to repair a solar panel on the International
Space Station. When the têther connecting the astronaut to the space
station becomes unattached, the astronaut, still holding the tool kit, starts
to float away at 0.2 m/s. Calculate the velocity with which the astronaut
must throw the tool kit in order to float back toward the space station at
0.1 m/s. Show your calculations and include units in your answer.
*
Answer:
v₃ = 9.62[m/s]
Explanation:
To solve this type of problem we must use the principle of conservation of linear momentum, which tells us that the momentum is equal to the product of mass by velocity.
We must analyze the moment when the astronaut launches the toolkit, the before and after. In order to return to the ship, the astronaut must launch the toolkit in the opposite direction to the movement.
Let's take the leftward movement as negative, which is when the astronaut moves away from the ship, and rightward as positive, which is when he approaches the ship.
In this way, we can construct the following equation.
[tex]-(m_{1}+m_{2})*v_{1}=(m_{1}*v_{2})-(m_{2}*v_{3})[/tex]
where:
m₁ = mass of the astronaut = 157 [kg]
m₂ = mass of the toolkit = 5 [kg]
v₁ = velocity combined of the astronaut and the toolkit before throwing the toolkit = 0.2 [m/s]
v₂ = velocity for returning back to the ship after throwing the toolkit [m/s]
v₃ = velocity at which the toolkit should be thrown [m/s]
Now replacing:
[tex]-(157+5)*0.2=(157*0.1)-(5*v_{3})\\(5*v_{3})= 15.7+32.4\\v_{3}=9.62[m/s][/tex]
The velocity with which the astronaut must throw the tool kit is 9.62 m/s.
The given parameters:
Mass of the astronaut and space suit, m₁ = 157 kgMass of the tool kit, m₂ = 5 kgVelocity of the astronaut and tool kit, v = 0.2 m/sVelocity of the astronaut and space station, u₁ = -0.1 m/sApply the principle of conservation of linear momentum to determine the velocity of the tool kit;
[tex]m_1 u_1 + m_2u_2 = v(m_1 + m_2)\\\\-0.1(157) \ + 5u_2 = 0.2(157 + 5) \\\\-15.7 + 5u_2 = 32.4\\\\5u_2 = 32.4 + 15.7\\\\5u_2 = 48.1\\\\u_2 = \frac{48.1}{5} \\\\u_2 = 9.62 \ m/s[/tex]
Thus, the velocity with which the astronaut must throw the tool kit is 9.62 m/s.

What is the mathematical relationship between wavelength and velocity? Inverse, horizontal, linear or quadratic? I NEED MAJOR HELP PLZ HELP ME THANK U
Answer: Wavelength is the measure of the length of a complete wave cycle. The velocity of a wave is the distance traveled by a point on the wave. In general, for any wave the relation between Velocity and Wavelength is proportionate. It is expressed through the wave velocity formula.
Explanation: For any given wave, the product of wavelength and frequency gives the velocity. It is mathematically given by wave velocity formula written as-
V=f×λ
Where,
V is the velocity of the wave measure using m/s.
f is the frequency of the wave measured using Hz.
λ is the wavelength of the wave measured using m. Velocity and Wavelength Relation
Amplitude, Frequency, wavelength, and velocity are the characteristic of a wave. For a constant frequency, the wavelength is directly proportional to velocity.
Given by:
V∝λ
Example:
For a constant frequency, If the wavelength is doubled. The velocity of the wave will also double.
For a constant frequency, If the wavelength is made four times. The velocity of the wave will also be increased by four times.
Hope you understood the relation between wavelength and velocity of a wave. I truely hope this helps you out tho! Goodluck!
Pete Zaria applies a 4.0-N force to a 1.0-kg mug of root beer to accelerate it over a distance of 1.0-meter along the countertop. Determine the work done by Pete on the mug and the mug's final kinetic energy and final velocity. PSYW
Answer:
Work done = 4 J
Final Kinetic Energy = 4 J
Explanation:
From the question,
Work done = force × distance
W = F×d................... Equation 1
Given: F = 4.0 N, d = 1.0 meter.
Substitute these values into equation 1
W = 4×1
W = 4 Joules.
Also,
Kenetic Energy = 1/2 × mass × velocity×velocity.
K.E = 1/2(mv²)........... (2).
But,
F = ma
Where F = 4 N, m = 1 kg.
a = 4/1 = 4 m/s².
Using,
v² = u² + 2as............. Equation 3
Where u = 0 m/s, a = 4 m/s², s = 1 m.
Substitute into equation 3
v² = 0² +2×4×1
v² = 8
v = √8 m/s.
Substitutting into equation 2
K.E = 1/2(1)(√8)²
K.E = 1/2(8)
K.E = 4 J.
Hence the work done and the Final Kinetic energy are thesame = 4 J
The work done by the Pete is 4.0 J. And its final velocity and kinetic energy are 2.82 m/s and 3.97 J respectively.
Given data:
The force applied by the Pete Zaria is, F = 4.0 N.
The mass of mud is, m = 1.0 kg.
The distance of the countertop is, s = 1.0 m.
The work by the Pete on the mug is equal to the product of applied force and the distance covered by the mug along the rooftop. Therefore,
W = F × s
W = 4.0 × 1.0
W = 4.0 J
Now, apply the third kinematic equation of motion to obtain the final velocity of the mug as,
[tex]v^{2} = u^{2}+2as[/tex]
Here, a is the magnitude of acceleration and its value is,
F = ma
4.0 = (1.0)a
a = 4.0 m/s²
Now,
[tex]v=\sqrt{0^{2}+(2 \times 4 \times 1)}\\\\v = 2.82 \;\rm m/s[/tex]
Now. the kinetic energy of the mug is calculated as,
[tex]KE = \dfrac{1}{2}mv^{2}\\\\KE = \dfrac{1}{2} \times 1.0 \times 2.82^{2}\\\\KE = 3.97 \;\rm J[/tex]
Thus, we can conclude that the work done by the Pete is 4.0 J. And its final velocity and kinetic energy are 2.82 m/s and 3.97 J respectively.

A plane is traveling at a velocity of 90 m/s. It accelerates at a constant rate of 1.5 m/s2 until its velocity reaches 500 m/s. What distance did the plane cover while it was accelerating?
Answer:
The distance the plane covered while it was accelerating is 80,633.3 m
Explanation:
Given;
initial velocity of the plane, u = 90 m/s
acceleration of the plane, a = 1.5 m/s²
final velocity of the plane, v = 500 m/s
The distance covered by the plane is given as;
v² = u² + 2ad
where;
d is the distance covered by the plane;
500² = 90² + 2(1.5)d
500² - 90² = 3d
241900 = 3d
d = 241900 / 3
d = 80,633.3 m
Therefore, the distance the plane covered while it was accelerating is 80,633.3 m

Dos cargas q1= 5 Milicoulombios y q2 = 6 Milicoulombios, se encuentran separadas 4 cm y sufren una fuerza entre ellas. ¿Cuál será el valor de la fuerza entre ambas cargas? ¿Existirá una fuerza de atracción o de repulsión? ¿Por qué?
Answer:
El valor de la fuerza entre ambas cargas es 168,750,000 N.
Ambas cargas son positivas, por lo que entre ellas existirá una fuerza de repulsión.
Explanation:
Los responsables de todos los fenómenos eléctricos son los electrones, porque pueden escapar de la órbita del átomo y son mucho más ligeros que las otras partículas.
La carga eléctrica es una propiedad física propia de algunas partículas subatómicas que se manifiesta mediante fuerzas de atracción y repulsión entre ellas. La materia cargada eléctricamente es influida por los campos electromagnéticos, siendo a su vez, generadora de ellos.
Entre dos o más cargas aparece una fuerza denominada fuerza eléctrica cuyo módulo depende del valor de las cargas y de la distancia que las separa, mientras que su signo depende del signo de cada carga.
La fuerza entre dos cargas se calcula como:
[tex]F=k*\frac{Q*q}{d^{2} }[/tex]
donde:
F es la fuerza eléctrica de atracción o repulsión y se mide en Newtons (N). Q y q son lo valores de las dos cargas puntuales y se miden en Culombios (C). d es el valor de la distancia que las separa y se mide en metros (m)k es una constante de proporcionalidad llamada constante de la ley de Coulomb. Depende del medio en el que se encuentren las cargas. Para el vacío k es aproximadamente 9·10⁹ N·m²/C² utilizando unidades en el S.I.Siendo 1 millicoulomb [mC] = 0,001 coulomb [C] y 100 cm= 1 m, en este caso sabes:
Q= 5 mC= 0.005 Cq= 6 mC= 0.006 Cd= 4 cm= 0.04 mReemplazando:
[tex]F=9*10^{9}\frac{N*m^{2} }{C^{2} } *\frac{0.005C*0.006C}{(0.04m)^{2} }[/tex]
F= 168,750,000 N
El valor de la fuerza entre ambas cargas es 168,750,000 N.
Las cargas del mismo signo se repelen, mientras que las cargas con diferente signo se atraen. En este caso ambas cargas son positivas, por lo que entre ellas existirá una fuerza de repulsión.
If an object accelerates from rest, with a constant of 8 m/s2, what will its velocity be after 35s?
Answer:
Its speed will be 280 m/s
Explanation:
Constant Acceleration Motion
It's a type of motion in which the speed of an object changes by an equal amount in every equal period of time.
If a is the constant acceleration, vo the initial speed, vf the final speed, and t the time, vf can be calculated as:
[tex]v_f=v_o+at[/tex]
The object accelerates from rest (vo=0) at a constant acceleration of [tex]a=8\ m/s^2[/tex]. The final speed at t=35 seconds is:
[tex]v_f=0+8*35[/tex]
[tex]v_f=280\ m/s[/tex]

A 45kg skater and a 60kg skater are standing still, holding hands on frictionless ice. They push away from each other in opposite directions. If the 45kg skater was measured traveling at 3.5 m/s, how fast was the 60 kg skater traveling?
Answer:
The 60 kg skater is traveling at 2.63 m/s in the opposite direction from the 45 kg skater.
Explanation:
The velocity of the 60 kg skater can be found by conservation of linear momentum:
[tex]P_{i} = P_{f}[/tex]
[tex]m_{a}v_{i_{a}} + m_{b}v_{i_{b}} = m_{a}v_{f_{a}} + m_{b}v_{f_{b}}[/tex] (1)
Where:
[tex]m_{a}[/tex]: is the mass of the first skater = 45 kg
[tex]m_{b}[/tex]: is the mass of the second skater = 60 kg
[tex]v_{i_{a}}[/tex]: is the initial speed of the first skater = 0 (he is standing still)
[tex]v_{i_{b}}[/tex]: is the initial speed of the second skater = 0 (he is standing still)
[tex]v_{f_{a}}[/tex]: is the final speed of the first skater = 3.5 m/s
[tex]v_{f_{b}}[/tex]: is the final speed of the second skater =?
By replacing the above values into equation (1) and solving for [tex]v_{f_{b}}[/tex] we have:
[tex]0 = m_{a}v_{f_{a}} + m_{b}v_{f_{b}}[/tex]
[tex]v_{f_{b}} = \frac{-m_{a}v_{f_{a}}}{m_{b}} = \frac{-45 kg*3.5 m/s}{60 kg} = -2.63 m/s[/tex]
The minus sign is because the 60 kg skater is moving in the opposite direction from the other skater.
Therefore, the 60 kg skater is traveling at 2.63 m/s in the opposite direction from the 45 kg skater.

A person wants to find the width of the lake by shouting and listening for the echo from the far side. If his echo returns after 2 seconds how wide is the lake? (Velocity of sound is 340 m/sec)
Answer:
The width of the lake is 340 m
Explanation:
Constant Velocity Motion
It occurs when an object travels the same distance every equal interval. For example, if it travels 5 m in one second, then 10 m in two seconds, etc., it has a constant velocity.
The speed of the sound is assumed as v=340 m/s and the person measures the time that a sound goes and comes from the edge of a lake as t=2 seconds. The distance it travels is:
d = v.t
d = 340 m/s * 2 s
d = 680 m
But that distance is twice the width of the lake, the real measured width is 680 m / 2 = 340 m
The width of the lake is 340 m
