A uniform thin rod of length L = 40.0 cm and mass M = 800 g is pinned so that it can swing about a point that is one-third of the way from one end of the rod. You pull the rod away from equilibrium by a small angle and release it, so that the rod swings back and forth. (a) What is the period of the rod’s motion as it swings back and forth? (b) What is the length...

without friction about an axis through its midpoint and
perpendicular to the rod. A horizontal spring, assumed massless and
with force constant k, is attached to the lower end of the rod,
with the other end of the spring attached to a rigid support.
