Homework Help: Simple Pendulum equation

  1. Apr 20, 2005 #1
    A pendulum has a period of 1.8 s.

    a) Its mass is doubled. What is its period now?

    b) Its length is doubled. What is its period now?

    The original pendulum is taken to a planet where g = 16 m/s2.
    c) What is its period on that planet?
