Question

A bill performs 13,000 joules of work pulling a wagon for 14 seconds. What is the bulls power?

Answer 1

By definition, the power is the speed of work:

$$P = \dfrac{W}{t}$$

where $W = 13000J$ is the work done, and $t = 14s$. Thus, obtain:

$$P = \dfrac{13000}{14} = 929W$$

Answer. 929 W.
