Calculate the work required to be done to stop a car of1500 kgmoving at the velocity of60 km/h?

When a object is moving with a constant velocity, it possess K.EK.E=12×m×v2So, in order to bring the object to rest i.e its same magnitude of energy is required so, as the final final energy comes to zero.v=60km/hr=16.66m/sSo, magnitude of work that needs to be done=12×m×v2Hence, work required to stop the car=12×1500×16.662=208166.7J=208.17kJ
