Question

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)

Answer 1

`P=7.35* 10^(3)\ W`

Step-by-step explanation:

Given that,

Mass,
`m=1.5* 10^2\ kg`

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 :

`P=(W)/(t)\\\\P=(mgh)/(t)\\\\P=(1.5* 10^2* 9.8* 15)/(3)\\\\P=7.35* 10^(3)\ W`

So, the power of the motor is equal to
`7.35* 10^(3)\ W`.
