A simple pendulum oscillates with an amplitude of 30 degrees. If the length of the string is 1.0m. Calculate the velocity of the pendulum bob at its lowest point.

Question

bobpursley · Answer

Well, at 30 degrees, its height is L-Lcos30 so its potential energy is mg(L-Lcos30) and that is equal to the KEnergy at the bottom... mgL(1-cos30)=1/2 m v^2 so calculate velocity v
