A 7 kg, 1.1 m long rod is supported on a knifeedge at its midpoint. A 7.4 kg ball of clay isdropped from rest from a height of 1.9 m andmakes a perfectly inelastic collision with therod 0.4 m from the point of support.Find the magnitude of the angular momentum of the rod and clay system about thepoint of support immediately after the inelastic collision. The acceleration of gravity is 9.81 m/sAnswer in units of J s.
