Answer:

75Watts

Step-by-step explanation:

Given parameters:

Time = 12s

Force applied = 20N

Height = 45m

Unknown:

Power output = ?

Solution:

Power is defined as the rate at which work is done.

It is mathematically expressed as;

Power =
(work done)/(time)

Work done = force x distance = 20 x 45 = 900J

Power =
(900)/(12) = 75Watts
