How to find the velocity of a pendulum...need help!
A 3.60 m long pendulum with a 1.25 kg bob is pulled sideways until it is displaced 1.80 m horizontally from its rest position. If the bob is released, calculate the speed of the bob when it is 0.250 m about it's rest position.
I found the potential energy when it passes through rest position= 5.91 J
and the velocity when it passes through rest position is 3.08 m/s. I don't know how to find it at 0.250 m & need help please!
