work done = increase in kinetic energy
= (1/2) m (V2^2-V1^2)
V2 = 72/3.6 meters/second
V1 = 54/3.6 meters/second
m = 1500 kg
then answer will be in Joules
calculate the velocity of a car increases from 54km 1hr to 72 km/hr if the mass of the car is 1500kg find the work done to increase the velocity
