# Calculating Constant speed of an Elevator Rising

## Homework Statement

The motor for an elevator can produce 14kW of power. The elevator has a mass of 1100 kg, including its contents. At what constant speed will the elevator rise?

## Homework Equations

I'm not really sure. Probably Gravitational potential = mgh. Kinetic energy = 1/2mv^2 because its looking for speed.

## The Attempt at a Solution

I'm really not sure. It doesn't seem like enough information is given to solve for anything. There's probably some algebraic manipulation I'm missing.

Consider work done per second (14 kJ) - what increase in height does that correspond to (14kJ = mgh)?

-S
