A thin stick of mass M = 4.3 kg and length L= 1.7 m is hinged at the top. A piece of clay, mass m =0.7 kg and velocity V = 4.0 m/s hits the stick a distance x = 1.00 m from the sticks and hinge to it.
1) What is the angular velocity of the stick immediately after the collision?
2) What is the ratio of the final mechanical energy to the initial mechanical energy?
