###### FREE Expert Solution

In this problem, we have to deal with force, distance, time, and power. We'll require an expression for the work and power.

Power:

$\overline{){\mathbf{P}}{\mathbf{=}}\frac{\mathbf{W}}{\mathbf{t}}}$

Work:

$\overline{){\mathbf{W}}{\mathbf{=}}{\mathbf{F}}{\mathbf{d}}}$
