A uniform rod of mass M and length L is initially horizontal, with its left end resting on the edge of a table, and its right end being held by your hand. Suddenly, you let go of the rod. Right after its release: (a) Find the the torque on the rod calculated about its left end. (b) What is its angular acceleration α = ̈φ about its left end? (c) Determine the vertical acceleration of the rod’s center of mass.

A uniform rod of mass M and length L is initially horizontal, with its left end resting on the edge of a
table, and its right end being held by your hand. Suddenly, you let go of the rod. Right after its release: (a) Find the
the torque on the rod calculated about its left end. (b) What is its
(c) Determine the vertical acceleration of the rod’s center of mass. (d) Based on the previous part, what is the normal force exerted by the table on the rod? (It might help to know that the rotational inertia of a uniform rod, rotated about one end, is I = M L2/3, and that L = Iω.)
