HELP!!

An electric motor is used to lift an elevator and
occupants (mass = 1.50 x 10kg) to a helght of
15.0 m in 30.0 s at a constant velocity. What is
the power output of the motor? I know the answer I just need someone to show me the steps so I understand how to solve this


Answer: (7.35 x 10^3 W)

Respuesta :

Answer:

[tex]P=7.35\times 10^{3}\ W[/tex]

Explanation:

Given that,

Mass, [tex]m=1.5\times 10^2\ kg[/tex]

It lifts to a height of 15 m in 3 s

We need to find the power of the motor. The formula for power is given by :

[tex]P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{1.5\times 10^2\times 9.8\times 15}{3}\\\\P=7.35\times 10^{3}\ W[/tex]

So, the power of the motor is equal to [tex]7.35\times 10^{3}\ W[/tex].
