Question 2

A uniform meter stick is pivoted to rotate about a horizontal axis through the 25-cm mark on the stick. The stick is released from rest in a horizontal position. The moment of inertia of a uniform rod about an axis perpendicular to the rod and through the center of mass of the rod is given by (1/12)ML2 . Determine the magnitude of the initial angular acceleration of the stick.
a. 17 rad/s2
b. 13 rad/s2
c. 15 rad/s2
d. 19 rad/s2
e. 23 rad/s2
