Answer:

Average Power =581.6W

Explanation:

Power is the rate of doing work.

Power [tex]=\frac{W}{t}[/tex]

W = F*S

Power [tex]=\frac{F*S}{t}[/tex]

Where F is force, S is distance, t is time

F= weight of the student= 727N

S=12m,    t= 15sec

Power [tex]=\frac{727*12}{15}[/tex]

Power =581.6W
