A thin rod (length is 1.50 m) is oriented vertically, with itsbottom end attactched to the floor by means of a frictionlesshinge. The mass may be ignored, compared to the mass of theobject fixed to the top of the rod. the rod, starting from rest,tips over and rotates downward.
(a) What is the angular velocity just before it strikes the floor?
(b) What isthe magnitude of the angular acceleration of the rod just before it strikes?
