A 1500 kg truck, cruising at 20.0 m/s, approaches a 0.450 km long hill inclined at 5.74?. To get to the top, the driver puts the pedal to the metal , accelerating to 25.0 m/s as he crests the hill. Use Energy methods to solve the problem.

a) how much useful work did the engine do as the truck climbed the hill?

b) what was the power output of the engine?

c) what average force was applied to the drive wheels?

d) if the truck was 22.6% efficient, what is the power rating of the engine in horsepower?
