Asked by Laura

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?
Answered by bobpursley
KE lowest point: 1/2 m v^2

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