The power output of second motor is 9.8 [tex]\times[/tex] 10^3 W.
Explanation:
Power is defined as the rate of doing electric work. I short it can be viewed as
Power = work done / time
Work done is the product of mass, gravity, and height. (i.e. mgh)
Given that m = 1000 kg, h = 10 m, g = 9.8 m / s^2, t = 10 s
Power = work done / time
= (m [tex]\times[/tex] g [tex]\times[/tex] h) / time
= (1000 [tex]\times[/tex] 9.8 [tex]\times[/tex] 10) / 10
power = 9800 W = 9.8 [tex]\times[/tex] 10^3 W.
