Answer:
Correct answer: Third statement P = 4900 W
Explanation:
Given:
m = 500 kg the mass of the elevator
h = 10 m reached height after t = 10 seconds
P = ? power of the motor
The formula for the calculating power of the motor is:
P = W / t
since work is a measure of change in this case of potential energy then it is:
W = ΔEp = Ep - 0 = Ep
In this case we must take g = 9.81 m/s²
Ep = m g h = 500 · 9.81 · 10 = 49,050 W ≈ 49,000 W
Ep ≈ 49,000 W
P = Ep / t = 49,000 / 10 = 4,900 W
P =4,900 W
