Answer:
122.5 kW
Explanation:
m = mass of the loaded elevator = 2.50 x 10³ kg = 2500 kg
t = time taken to raise the elevator = 10.0 s
h = height gained by the elevator = 50.0 m
g = acceleration due to gravity = 9.8 m/s²
Power spent is given as
P =
Inserting the values
P =
P = 122500 Watt
P = 122.5 kW (Since 1 kW = 1000 W)
