In a science museum, you may have seen a Foucault pendulum,which is used to demonstrate the rotation of the earth. In onemuseum's pendulum, the 120 kg bob swings from a 18.2-m long cablewith an amplitude of 5.5 degrees. What is the maximum velocity,kinetic energy, and when the bob is at its maximumdisplacement, how much higher is it than when it is at itsequilibrium position?
