Consider the rod in Figure P9.22, but now assume it starts from rest in the “up” position (i.e., pointing vertically upward from the hinge). If the rod is then given a very small push, what is the linear speed of the end of the rod when it reaches the bottom of its circular path?

(reference figure P9.22)
