Answer:
38Watts
Explanation:
Given parameters:
Mass = 75kg
height = 8.5m
time = 165s
Unknown:
Power = ?
Solution:
Power is the rate at which work is done.
Power = [tex]\frac{work done}{time}[/tex]
Work done = mgh
m is the mass
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
P = [tex]\frac{75 x 9.8 x 8.5}{165}[/tex] = 38Watts
