When Justine is ice-skating, her final velocity if she accelerates at a rate of 2.0 m/s² for 3. 5 seconds is 7 m/s and it would take Jesse 5.4 seconds to stop the bicycle moving at an initial velocity of 13.5 m/s by accelerating at -2.50 m/s².
To find Justine's final velocity, we can use the equation:
v = u + at
where v is the final velocity, u is the initial velocity (which is assumed to be 0 in this case), a is the acceleration, and t is the time. So
v = 0 + (2.0 m/s²) × (3.5 s) = 7.0 m/s
To find the time it would take for Jesse to bring his bicycle to a stop, we can use the equation:
v = u + at
where v is the final velocity (which is assumed to be 0 m/s in this case as bicycle is brought to a stop), u is the initial velocity, a is the acceleration, and t is the time.
Given that a = -2.5 m/s² (negative sign indicates deceleration) and u = 13.5 m/s.
so t = (v - u) / a = (0 - 13.5 m/s) / -2.5 m/s² = 5.4 seconds
It would take Jesse 5.4 seconds to bring his bicycle to a complete stop.

A 2.6-mm-diameter sphere is charged to -4.4 nC. An electron fired directly at the sphere from far away comes to within 0.32 mm of the surface of the target before being reflected.
a. What was the electron's initial speed?
b. At what distance from the surface of the sphere is the electron's speed half of its initial value?
c. What is the acceleration of the electron at its turning point?
The correct answer to the given question is -6.944 * 10^-28 Joules
a. To find the electron's initial speed, we can use the conservation of energy. The initial kinetic energy of the electron must equal the final potential energy of the electron at its closest approach to the sphere.
Ki = 1/2 * me * v^2
v = sqrt(2Ki/me)
Ki = qe * V = (1.6 x 10^-19 C) * (-4.4 x 10^-9 C) = -6.944 x 10^-28 J
b. At the point where the speed of the electron is half of its initial value, the kinetic energy of the electron is half of its initial value. Therefore,
Ki/2 = 1/2 * me * (v/2)^2
we can solve for the distance from the surface of the sphere using the same equation as in part a, and substituting Ki/2 and v/2 for Ki and v respectively
c. The acceleration of the electron at its turning point can be found using the equation for centripetal acceleration:
a = v^2/r
where a is the acceleration, v is the speed of the electron, and r is the distance of the electron from the center of the sphere at its closest approach. We can use the value of v from part a and the distance from part b to find the acceleration.

The thermal energy in a substance is the whole kinetic energy of all the particles in the substance. If we warm a substance or object, as each particle speeds up, the average speed of the particles (temperature) raises, and accordingly the total speed (kinetic energy) of the particles (thermal energy).

According to the question the rotational kinetic energy of a 12-kg motorcycle wheel is 809.14 J
What does rotational kinetic energy?The SI unit for rotational kinetic energy is the joule (J). The rotating kinetic energy formula has a similar structure to a translational kinetic energy equation. Kinetic energy is created by spinning objects around an axis. This type of energy is influenced by the object's mass, weight, and center of mass angle with respect to the axis.

Angular velocity (ω) -120rad/s
inner radius = 0.280 m
outer radius = 0.330 m.
By using the formula
I = ½*M (r1² + r2²)
I = ½ *(12) * (0.2802 + 0.3302)
I = 1.1238 Kgm2

Assuming that the astronaut starts from rest, find the final speed of the astronaut after throwing the tank.
The final speed of the astronaut after throwing the oxygen tank can be calculated using the conservation of momentum principle.
This principle states that the total momentum of an isolated system remains constant if no external forces act on the system.The momentum of the oxygen tank is given by the equation.
p_t = m_t*vThe conservation of momentum principle states that the initial momentum of the system is equal to the final momentum of the system.
p_i = p_f
The final momentum of the system is the momentum of the astronaut-tank system after the astronaut throws the tank.
p_f = (m_a + m_t)v_f = (64.5 + 12) * v_f = 76.5 * v_f
So the final momentum of the system is equal to the momentum of the oxygen tank.
p_t = m_tv = 1214.9 = 178.8We can set the two equations equal to each other and solve for v_f

In general, the work done by a force on an object between two points does depend on the path taken by the object between the two points. For the special case of conservative forces, we have seen that the work does not depend on the path.
Therefore, we can define, for conservative forces, an associated potential energy that, for a given object, depends only on its location. In particular, when a conservative force acts on an object as it moves between two points, we define the define the change in potential energy associated with that force as minus the work done by that force between those two points.

The rate at which an object's position changes when observed from a specific point of view and when measured against a specific unit of time is known as its velocity.
How do you find a velocity of an object?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound).
By dividing the amount of time it took the object to go a certain distance by the overall distance, one can calculate the object's initial velocity. V is the velocity, d is the distance, and t is the time in the equation V = d/t.
An object's velocity can alter depending on whether it moves faster or slower or in a different direction. An object can move faster, slower, or remain stationary by being pushed or pulled in one direction or the other. Or to put it another way, a thing moves because of a force.

f = 25 N
How can you determine the total force exerted on an object?The vector sum of all forces acting on an object is known as the net force. As a result of the fact that a force is a vector and that two forces with identical magnitudes and opposing directions cancel each other out, the net force is the sum of all the forces, or put another way, the net force is the sum of all the forces.

At a particular speed, a jumbo jet can travel its own length in 20 seconds. At this same speed, the jumbo jet taxied completely past a 710-foot-long hangar in 70 seconds, as shown. What is the length of the jumbo jet in feet
A jumbo jet can fly its whole length in 20 seconds at a certain speed and has a 284-foot length. The big jet taxied completely past a 710-foot-long hangar in 70 seconds while travelling at the same speed.
In physics, you can get average speed by dividing the total distance travelled by the total time needed to travel that distance. Speed is the rate of change in an object's position, expressed in metres per second. The rate at which an object travels a distance is considered its speed. High speed describes an object that is travelling quickly.
P should represent the plane's length in feet.
20p = (710+p)/20p = 14200+20p 50p = 14200 p = 284ft
