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).
Homework Equations
K= (1/2)mv^2
U= mgh
ma=v^2/r=F
The Attempt at a Solution
K + U = Total Energy
1618.871 + 2352 = 3970.871 J
i got really lost on this one
