A 630 kg car pulling a 535 kg trailer accelerates forward at a rate of 2.22 m/s2. Assume frictional forces on the trailer are negligible. Calculate the net force (in N) on the car.

Answers

Answer 1

To calculate the net force on the car, we can use Newton's Second Law, which states that force equals mass times acceleration (F=ma). First, we need to find the total mass of the car and trailer combined: Total mass = 630 kg (car) + 535 kg (trailer) = 1165 kg

Now we can plug in the values we have into the formula:

F = ma
F = 1165 kg x 2.22 m/s^2

F = 2583.3 N

Therefore, the net force on the car is 2583.3 N.

To calculate the net force (in N) on a 630 kg car pulling a 535 kg trailer and accelerating forward at a rate of 2.22 m/s², follow these steps:

1. Determine the total mass of the car and trailer: 630 kg (car) + 535 kg (trailer) = 1165 kg (total mass)
2. Apply Newton's second law, which states that the net force (F) equals the mass (m) multiplied by the acceleration (a): F = m × a
3. Plug in the total mass and acceleration values: F = 1165 kg × 2.22 m/s²
4. Calculate the net force: F = 2586.3 N

So, the net force on the 630 kg car pulling a 535 kg trailer and accelerating forward at a rate of 2.22 m/s² is 2586.3 N.

Answers

Answer:

1. Net force= 6 N to left

2. Unbalanced

3. Both people must apply same magnitude of forces in opposite direction which causes net force to be 0.

Explanation:

Since both forces have opposite direction then we have to subtract the magnitude and consider the direction of vector that has greatest magnitude. In this case, the left side (13N) has more magnitude than the right side (7N). Hence:

[tex] \displaystyle{ \sum \vec F = 13 \: \text{N}- 7\: \text{N}= 6 \: \text{N to left}}[/tex]

The vector arrow of net force will point to left side with magnitude of 6 N.

Since the net force is not zero. This means that the force is not balanced as an object still changes its motion from resting to moving. A balanced force would mean the net force is zero and an object will always remain as same condition. This can be referred to first Newton's law of motion.

We can make the force balanced by having both people acting same magnitude of force in opposite direction. The equation must result in:

[tex] \displaystyle{ \left | \vec F \right | = \left| - \vec F \right| }[/tex]

Magnitude of forces must equal for both sides and also have to act in opposite direction which causes net force to be zero:

15. 5 seconds ago the velocity of the jet was 4250 m/s

What are the kinematic equations of motion?

The kinematic equations of motion are;

v = u + a·t

s = u·t + (1/2)·a·t²

v = u + 2·a·s

Where;

v = The final velocity

u = The initial velocity

s = The distance

t = The time of the motion

a = The acceleration

8. The runner's rate of acceleration = 2 m/s²

The runner's top speed = 10 m/s

The required kinematic equation is; t = (v - u)/a

Where;

t = The time duration

a = The acceleration = 2 m/s²

v = The final velocity = The runner's top speed = 10 m/s

u = The initial velocity of the motion = 0 (assumption that the runner starts from rest)

Therefore;

t = (10 - 0)/2 = 5

It takes the runner 5 seconds to get up to full speed

9. The speed of the bullet when it hits the bystander, v = 250m/s

The time at which the bullet was shot out of the high powered rifle, t = 1.5 seconds

The initial velocity of the bullet, u = 0m/s (The bullet is initially at rest in the gun)

The acceleration, a = (v - u)/t

Acceleration = (250 - 0)/1.5 = 166.[tex]\overline{6}[/tex]

The acceleration of the bullet is 166.[tex]\overline{6}[/tex] m/s²

10. The acceleration of the person as he falls, a = 10 m/s²

The speed at which the person was travelling as he hits the ground, v = 600 m/s

Time after which the person hits the ground, t = 5 seconds

v = u + a·t
u = v - a·t

Therefore; u = 600 - 10 × 5 = 550

The initial velocity of the person is 550 m/s

11. The acceleration rate, a = 2 m/s²

Initial velocity, u = -6m/s

Final velocity, v = 10m/s

t = (10 - (-6))/2 = 8

The time it takes the skater is 8 seconds

12. The initial angular velocity of the fan, ω₁ = 9 rev/sec

1 rev = 2·π rad, therefore;

ω₁ = 2·π × 9 rad/s = 18·π rad/s

The time after which the fan stops, Δt = 3 seconds

The final angular velocity of the fan, ω₂ = 0

The angular acceleration of the fan, α = (ω₂ - ω₁)/Δt

Therefore; α = (0 - 18·π)/3 = -6·π

The acceleration of the fan is -6·π rad/s²

13. The time it takes the zebra to hit the ground = 10 seconds

The acceleration due to gravity, g = 9.8 m/s²

The initial velocity of the zebra, u = 0 m/s

Therefore;

The velocity with which the zebra hits the ground, v = 9.8 × 10 = 98

The zebra hits the ground moving at 98 m/s

14. Initial speed of the school bus, u = 50 m/s

The time it takes the school bus to come to rest = 0.5 seconds

The acceleration. a = (0 m/s - 50 m/s)/(0.5 s)) = -100 m/s²

15. The acceleration of the jet = 150 m/s²

Current velocity of the jet = 5000 m/s

The vectorial expression of velocity is the movement in space-time of an object or particle. The recognised unit of velocity magnitude is the metre per second (m/s) (also known as speed). The rate of speed can also be expressed in centimetres per second (cm/s). The pace at which an object's location changes as seen from a certain angle and as stated by a specific time unit (for example, 60 km/h northbound) is measured by its velocity, which is the direction in which it is travelling.

What is velocity in physics?

As a physical vector quantity, velocity must have a specified magnitude and direction. Speed is a coherent derived unit whose quantity is measured in metres per second (m/s or ms1) in the SI. Speed is the scalar absolute value (magnitude) of velocity (metric system). A vector is "5 metres per secon.

The vertical circle has a radius of 0.90 metres.

As the ball rotates vertically and continuously in a circular motion. As a result, the ball will move at the same speed at each point.

Consequently, the centripetal force ought to be constant at each location, that is,

mv2/R

Here, m stands for mass. R is the radius, and v is the speed.

The tension operating on the ball (towards the centre) and the gravitational force acting on it counteract this centripetal force. Thus,

mv2/R=T+mg

The tension should be zero for the minimal velocity. Thus,

mv2/R=mg

Simplify it as,

V2/R=g

V=√Rg

Assume that V is the initial velocity.

1/2mv2=mg(2R)+1/2m(√(gR^2 )

V=√5gR

G's squared value is 9.8 m/s. The ball must therefore move at a minimal speed in order to complete the circle:

V=5×9.8×0.90

V=44.1m/s

Two asteroids in space are 67,000m apart. One of the asteroids has a mass of 34,000kg and the other has a mass of 15,000kg. What is the force between them. In order to earn all credit show all your work.

Answers

Answer: The force between the two asteroids is 2.25 x 10^-5 N.

PLEASEEEE GIVE BRANLIEST

Explanation:

The force between two objects in space can be calculated using the formula:

F = G * (m1 * m2) / r^2

Where:

F = force between the two objects

G = gravitational constant (6.67 x 10^-11 Nm^2/kg^2)

m1 = mass of object 1

m2 = mass of object 2

r = distance between the two objects

So, in this case:

F = 6.67 x 10^-11 Nm^2/kg^2 * (34000 kg * 15000 kg) / (67000 m)^2

To calculate the force between the two asteroids, we need to substitute the values for m1, m2, and r into the formula.

F = 6.67 x 10^-11 Nm^2/kg^2 * (34000 kg * 15000 kg) / (67000 m)^2

F = (2.25 x 10^-5 N)

So the force between the two asteroids is 2.25 x 10^-5 N.

A 2250 kg cartraveling to the east slows down uniformly from 20 m/s to 5 m/s. How long does it take to decelerate if the braking force is 7500 N to the west?

A. 3 seconds
B. 4.5 seconds
C. 6 seconds
D. 7.5 seconds

Answers

The time taken for the car to decelerate is 4.5 seconds.

option B.

What is the acceleration of the car?

The acceleration of the car is calculated from Newton's second law of motion as follows;

F = ma

a = F / m

a = ( 7500 ) / ( 2250 )

a = 3.33 m/s²

The time taken for the car to slow down is calculated as follows;

v = u + at

at = v - u

t = ( v - u ) / a

where;

v is the final velocity u is the initial velocity

t = ( 20 - 5 ) / 3.33

t = 4.5 seconds

i'm behind a car and wish to pass so you turn to the left and pull into the passing lane without changing speed why does the distance increase between you and the car you're following

Answers

Since the component of your velocity along the road decreased slightly as there was a component across the road when you changed lanes, the distance increased.

Which element, which disrupts attention, raises risk when driving a car?Driving while distracted might raise the likelihood of a car accident. Distractions include anything that diverts your focus from operating a vehicle. Distracted driving includes a variety of activities, including as texting, chatting on the phone, using a navigation system, and eating while operating a vehicle.On the left, overtake traffic. Only when the open roadway is clearly signposted for two or more lanes of traffic in your direction are you allowed to pass on the right. You do not drive off the road to pass the vehicle in front of you when they are making a left turn.

The image of your face will be located 66.5 cm behind the front surface of the Christmas tree ball.

What is surface?

Surface is the outer layer of a physical object, such as a planet or a star. It is also the top layer of an object, such as the ground or a body of water. Surface can refer to the interface between two objects, such as the atmosphere and the ocean, or the interface between two materials, such as the air and the ground. The term can also refer to the top layer of a material, such as the skin of a human or the bark of a tree. In some cases, surface can refer to the way a material or object looks or feels, such as the smoothness of a rock or the texture of a fabric.

This is because of the principles of spherical mirrors; the image is located twice the distance behind the mirror as the object is in front of it. Therefore, the distance between your face and the image of your face is 58.0 cm (29.0 cm + 66.5 cm). The answer is expressed to two significant figures, and the appropriate units are included.
