Question

What is the horsepower of a 1,500 kg car that can go to the top of a 360 m high hill in exactly 1 min?

Answer 1

Answer:

W = m g h        work that must be done on car

P = W / t       power that must be input (in Watts)

P = m g h / t = 1500 kg * 9.8 m/s^2 * 360 m /  60 sec

P = 88,200 watts

P = 88,200 watts / 746 watts / hp = 118 hp
