# Calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 60 km/h?

The kinetic energy of the car is zero as it stops. So, the work done that is required to stop the car will be equal to its kinetic energy.

Given,

Mass of car, m = 1500 kg

Velocity of car, v = 60 km/h

We know that, when car is moving the car energy is in form of kinetic energy but to stop the car kinetic energy should be zero.Thus Work done= Kinetic energy

And ,

= 208333.3 J

Therefore, the value of the work required to stop the car is equal to kinetic energy of the car is 208333.3 J
