A thin rod of uniform mass density has length L = 1.20 m and mass M = 2.00 kg. It is pivoted about a horizontal frictionless pin through one end of the rod. The rod is released when it makes an angle of 36.8? with the horizontal.
a. What is the torque on the rod as it rotates about its end?
b. What is the angular acceleration of the rod at the instant it is released?
c. What is the tangential acceleration of the free end of the rod at the instant it is released?
