An 2.4 m long rod ofmass m1 = 17.0 kg, is supported on a knife edge at itsmidpoint. A ball of clay ofmass m2 = 2.2 kg is dropped from rest from a heightof h = 1.1 mand makes a perfectly inelastic collision with the rod 0.9 m fromthe point of support. Find the angular momentum of the rod and claysystem about the point of support immediately after the inelasticcollision.
