A pendulum is made from a uniform rod of mass m1 and a small block of mass m2 attached at the lower end?
(a) If the length of the pendulum is L and the oscillations are small, find the period of the oscillations in terms of m1, m2, L, and g?
(b) Check your answer to part (a) in the two special cases m1 >> m2 and m1 << m2?
