## What is a car of a of mass 1500kg traveling at 25m s collides with?

Solution: Car A of mass 1500 kg travelling at 25 m/s collides with another car B of mass 1000 kg travelling at 15 m/s in the same direction. After collision, the velocity of car a become 20m/s. The velocity of car B after collision is 22.

## How much work is done to stop a car weighing 1500 kg moving with a speed of 60 km h?

Hence, work required to stop the car =12×1500×16.662 =208166.7J=208.17kJ. Was this answer helpful?

## What is the kinetic energy of a 1500 kg car moving at 20 ms?

Therefore, the kinetic energy of the car is 300,000 J.

## What is the impulse necessary to stop a 1500 kg car traveling at 90 km per hour?

Thus, Impulse on the car will be 3.75×104kgms−1.

## What is collision formula?

From the conservation of momentum, the equation for the collision between two objects is given by: m1v1 + m2v2 = m1v’1 + m2v’2. From this expression, the initial and final velocities can be derived.

## What is the momentum of a 1200 kg car with a velocity of 25 m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

## What is the work done required to stop a car of 1500 kg moving at a velocity of 16 km per hour?

∴ The work done to stop the moving car = 208333 J.

## What amount of work is done to stop a car of 1000 kg moving with a speed of 72 km per hour?

W = 1 2 × 1000 × 20 × 20 = 400000 J.

## How much work is required to stop a car of 1000 kg moving with speed of 72 km h?

Expert-Verified Answer Work required to stop a car is 400000 Joule or 400 kilojoule.

## How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

## How do you calculate the kinetic energy of a car of mass 500 kg moving with a velocity?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ.

## What is the kinetic energy of a car of mass 1000 kg moving at 20 ms 1?

By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1. We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific calculator).

## What is the average braking force of a 1000 kg car moving at 20m s?

Therefore, the force applied by the brakes is 2000 N. Q. A car of mass 1000 kg moving with a velocity of 20 m/s is brought to rest by applying brakes in 10 seconds.

## What is the formula for impulse using speed?

By using momentum change: The formula to calculate impulse through momentum change is by calculating the mass of the body and the velocity. In this case, Impulse will be equal to the product of mass and velocity. So J= m*v.

## What is momentum equal to?

Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt).

## What is a car of mass 1000 kg moving with a velocity of 45km h?

A car of mass 1000 kg moving with a velocity of 45 km/h collides with a tree and comes to stop in 5 s. The force exerted by car is 2500 N. Force = mass × retardation ⇒F=1000 × (2. 5) ⇒F=2500 N The force exerted by the car on the tree is 2500 N.

## What is the change in momentum of a car of mass 1500 kg?

Final Momentum = 1500 × 20 kg. m/s = 30000 kg. m/s. The change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h = 30000 kg. m/s − 15000 kg.

## How do you calculate collision impact?

Calculate Your Crash Force The impact to your body in a crash is called crash force. Crash force is equal to your body weight multiplied by the speed of the vehicle.

## What is the formula for the momentum of a collision?

Before the collision, one car had velocity v and the other zero, so the centre of mass of the system was also v/2 before the collision. The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.
