→Answer :

Calculating the force.

→Given

Mass (m) = 65 kg.

Acceleration due to gravity (a) = 9.8 m/s²

Force (F) = ?

F = ma

F = (65)(9.8)

F = 637 N

Calculating Power.

→Given

Force (F) = 637 N

Time (t) = 0.63 mins or 39.6 s

Distance (d) = 12 m

Power (P) = ?

P = Fd / t

P = (637)(12) / 39.6

P = 7644 / 39.6

P = 193.03 W
