Given:
The work done by the man is W = 500 J
The time taken by the man is t = 8 s
To find the power.
Explanation:
The power can be calculated by the formula
[tex]P=\frac{W}{t}[/tex]On substituting the values, the power will be
[tex]\begin{gathered} P=\text{ }\frac{500}{8} \\ =\text{ 62.5 W} \end{gathered}[/tex]Thus, the power is B. 62.5 W
