Question

calculate the work to be done to increase the velocity of a 1500 kg car from 30 km/h to 60 km/h​

Answer 1

Solution: According to the Work-Energy theorem or the relationship between Kinetic energy and Work done - the work done on an object is the change in its kinetic energy. Hence, the work to be done to increase the velocity of a car from 30km / h to 60km / h is 156250 joule , if the mass of the car is 1500 kg.
