Answer:
245W
Explanation:
Given parameters:
Mass of his body = 50kg
Height of climb = 5m
Time = 10s
Unknown:
Power = ?
Solution:
Power is defined as the rate at which work is done;
Mathematically,
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
Work done = 50 x 9.8 x 5 = 2450J
Power = [tex]\frac{2450}{10}[/tex] = 245W
