A loaded elevator has a mass of 2.50 x 10^3 kg and is raised in 10.0s to a height of 50.0 m. How many kilowatts are required?
1 answer:
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)

Explanation:
Hello,
In this case, since we compute the required energy via:
Whereas m is the mass which here is 70 g, C the specific heat which for water is 4.184 J/(g°C) and ΔT is the temperature difference which is:
Therefore, the energy turns out:
