A large pendulum with a 200-lb gold-plated bob 12 inches in diameter is on display in the lobby of the United Nations building. Assume that the pendulum has a length of 78.4 ft. It is used to show the rotation of the Earth - for this reason it is referred to as a Foucault pendulum.
What is the full period of a pendulum with only half the length of the pendulum described above.
