Physics Olympiad #007 [Sliding Block Hits Hanging Stick]

A block of mass m moves with initial speed v0 on a smooth floor. A homogeneous rod of mass Big M and length Big L hangs freely from the ceiling and is initially at rest. The bar Big M is hit by the block m. Just a moment after the impact, the rod swings and the block comes to rest.
a. Check whether the case above is an elastic or inelastic collision?
b. Determine the maximum height to which a homogeneous rod swings?
