Potential and Kinetic Energy
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/sec2 as the gravitational constant. Your answer will be in foot-pounds since US units are being used.
If the ball is 20ft high
I just need to know how to do the math, I think the equation is
20lbs (32.2ft/sec^2) (20ft) =
