A large steel bar of length (ell) is hinged at one end to a wall. A mechanic

Question:

A large steel bar of length $\ell$ is hinged at one end to a wall. A mechanic holds the other end so that the bar is parallel to the ground and places a penny on the bar right at the end he is holding.

(a) What is the rotational acceleration of the bar when he lets go?

(b) Does the penny remain in contact with the bar after it is released?
