(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The rope of a swing is 3.00 m long. Calculate the angle from the vertical at which a 80.0 kg man must begin to swing in order to have the same KE at the bottom as a 1420 kg car moving at 1.51 m/s (3.38 mph).

2. Relevant equations

K= (1/2)mv^2

U= mgh

ma=v^2/r=F

3. The attempt at a solution

K + U = Total Energy

1618.871 + 2352 = 3970.871 J

i got really lost on this one
