Answer:
753.9Watts
Explanation:
Given parameters:
Mass of the student = 75kg
Height = 4m
Time = 4.9s
Unknown:
Power exerted by the student = ?
Solution:
To solve this problem, we must know that 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
h is the height
Power = [tex]\frac{75 x 9.8 x 4}{3.9}[/tex] = 753.9Watts
