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
