If a cart rolled down a ramp 5 meters high and flew off a a table at 3 meters high, what would its velocity be? please let me know where i go wrong, i was using the law of conservation of energy mgh1=mgh2+1/2mv2 mg(h1-h2)=1/2mv2 v=square root of 2g(h1-h2) where h1=5 and h2=3 i plugged in...

Hi guys. I need a few equations to complete a table. I am given numbers for: Fg (N) h (m) Fa (N) d(m) and I need to find: Work Output (J) Work Input (J) Effeciency If anyone has those three equations I could use it would be greatly appreciated.
