A rod of mass M and length L is hanging from one end on africtionless axis. We let the rod swing from an angle θ.At the lowest point of the swing the rod hits a clay balllying on the floor and stick to it.
a) What is the angular velocity of the rod right beforeit hits the ball?
b) What will be the angular velocity of the rod and theball after the collision?
c) How much energy was lost in this process?
d) What is the maximum height the rod and ball reach after the collision?
