To determine the power, we need to know the time which he did the energy in it

Using the definition of the power which is the change time rate of the energy

[tex]P=\frac{E}{t}[/tex]

in unit (J/sec) which equals to (watt)

Answer:

P = F / t

Explanation:

Hello! Let's calculate this! To calculate the power we need the force exerted per unit of time. For this we use the power formula

P = F / t

We lack the time to calculate it.

The units used is Joule / s = Watts. This is the unit of power.
