A Foucault pendulum is designed to demonstrate the effect of the Earth's rotation. A Foucault pendulum displayed in a museum is typically quite long, making the effect easier to see. Consider a Foucault pendulum of length 16 m with a 109-kg brass bob. It is set to swing with an amplitude of 3.1°.
(a) What is the period of the pendulum?
(b) What is the maximum kinetic energy of the pendulum?
(c) What is the maximum speed of the pendulum?
