## Homework Statement

A box is on top of a slope. The slope has NO FRICTION. V0 = 0 m/s, V = 4m/s.

MASS IS UNKNOWN

What is the height of the slope?

## Homework Equations

Equation for energy (i think)

## The Attempt at a Solution

I attempted to find the accelleration, but I do not know what the accelleration is for an object running down a slope with no friction.

The only force applying to the box is gravity, I think.

I am new to Physics. I tried solving it, but to no avail.

I know this can be solved without knowing the mass, but I don't know how! Help?
