At the low point in its swing, a pendulum bob with a mass of 0.2 kg has a velocity of 4 m/s What is the Kinetic at the low point? and Ignoring air resistance how high will the bob swing above the low point before reversing direction?

Answer 1

KE lowest point: 1/2 m v^2

How high? mgh= KE at lowest point, solve for h.
