Go up a hill
A car with a mass of
kg is going up a hill with an inclination of
° and a length of
m. The magnitude of work going up the hill with a speed of
km/h is
J. If the speed doubles to
km/h, what will be the magnitude of work
(in J)?

There is no change in Kinetic Energy, so we just have to see the change in the Potential Energy. In both the cases, we climb the same hill (with the same height). Thus, the change in Potential Energy is same in both the cases. Hence, the Work done is also the same in both the cases.
