Answer 1

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.

Step-by-step explanation:

The power can be calculated by the formula

`P=(W)/(t)`

On substituting the values, the power will be

`\begin{gathered} P=\text{ }(500)/(8) \\ =\text{ 62.5 W} \end{gathered}`

Thus, the power is B. 62.5 W
