Q17 of 33 Page 158

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,


= 208333.3 J

Therefore, the value of kinetic energy is 208333.3 J
