# Calculate height and velocity given kinetic and potential?

JohnDoe624

## Homework Statement

I have a table that needs to be filled out. In each column, potential and kinetic energy are given, but height and velocity are left blank. Ex: PE = 20 J, KE = 0 J, h = ?, V = ?

KE = 1/2mv^2
U = mgh

## The Attempt at a Solution

I'm totally stumped. How can I figure out either of these with no mass given?
