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

Answer:

18s

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  = $\frac{Work done}{Time taken}$

    Time taken  = $\frac{Work done }{Power}$

     Time taken  = $\frac{180}{10}$    = 18s
