Question

A hamster running on a wheel generated 180 J of work, but the hamster's power was only 10 W. How long did it take for the hamster to generate that much work?​

Answer 1

18s

Step-by-step explanation:

Given parameters:

Work done by hamster = 180J

Power of hamster = 10W

Uknown:

Time taken for the hamster to generate the work = ?

Solution:

Power can be defined as the rate at which work is being done by a body. It is related to both work done and time by the expression below;

Power =
`(Work done)/(Time taken)`

Time taken =
`(Work done )/(Power)`

Time taken =
`(180)/(10)` = 18s
