Question

The brakes on a bicycle apply 125N of frictional force to the wheels as the bicycle travels 14.0m. How much work have the brakes done on the bicycle

Answer 1

Answer:

1750J

Explanation:

Given

force = 125N

displacement = 14m

therefore,

according to formula of work,

Work = force * displacement

So,

Work = (125 * 14)J

So, Work = 1750J
