A 2.4 m long rod of mass m1 = 13.0 kg, is supported on a knife edge at its midpoint.
A ball of clay of mass m2 = 4.4 kg is dropped from rest from a height of h = 1.5 m and makes a perfectly inelastic collision with the rod 0.9 m from the point of support.
Find the angular momentum of the rod and clay system about the point of support immediately after the inelastic collision.
