Answer:
4950W
Explanation:
Given parameters:
Height = 100m
Time = 20s
Weight = 990N
Unknown:
Power = ?
Solution:
Power is the rate at which work is done.
Power = [tex]\frac{Work done }{time }[/tex]
Workdone = Force x distance
Input the parameter and solve for the workdone;
Workdone = 990 x 100 = 99000J
Now;
Power = [tex]\frac{99000}{20}[/tex] = 4950W
