Question

How powerful is an engine that can do 400 J of work in 10 seconds? Provide your answer in both "Watts" and "horsepower".)

Answer 1

To find the power of the engine we have to use the following formula:

Power = Work / Time

Power = 400J / 10s

Power = 40 Watts

To convert this power into horsepower, we can use the conversion factor: 1 horsepower (hp) = 745.7 Watts.

40/745.7 ≈ 0.053640874346252 hp

Answers:
