## Homework Statement

An elevator with a mass of 500kg goes up 30 stories in 12 seconds doing 12000J of work. Find how high the elevator goes.

## Homework Equations

I'm not exaclty sure what equations are needed for this question but in class we have been using these equations.

Ek=1/2mv^2

Ep=mgh

W=Fs

P=Fv

Totaly Mechanical Energy = Ep + Ek

we have also been ignoring other losses.

and other standard kinematic equations to work out velocity, acceleration, distance etc.

## The Attempt at a Solution

I would show my attempt at it but I've really got no clue and end up getting answers of like 2.45m which is obviously not the height of a 30 story building.

Sorry if this is a bit vague, I'm going off the top of my head.
