Answer:
The average power supplied is 100.8 W.
Step-by-step explanation:
Given that,
Height = 20.0 m
Time = 14.0 s
Mass = 7.20 kg
We need to calculate the average power
Using formula of average power
power = change in potential energy divided by time

Where, h = height
t = time
m = mass
Put the value into the formula


Hence. The average power supplied is 100.8 W.
