# Potential and Kinetic Energy

**Question description**

1. Suppose
each red ball weighs 20 lbs. Find the
potential energy *(PE)* for each ball
on each ramp. In this lab mass is given
in pounds and height is in feet, so use **32.2
ft/sec ^{2} as the gravitational constant**. Your answer will be in foot-pounds since US
units are being used.

I just need to know how to do the math, I think the equation is

20lbs (32.2ft/sec^2) (20ft) =
