Consider a thin 34 m rod pivoted at one end. A uniform density spherical object (whose mass is 5 kg and radius is 3.6 m) is attached to the free end of the rod. The moment of inertia of the rod about an end is I rod =1/3 mL^2 and the moment of inertia of the sphere about its center of mass is I sphere =(2/5) mr^2.
What is the angular acceleration of the rod immediately after it is released from its initial position of 61◦ from the vertical? The acceleration of gravity g = 9.8 m/s2.
Answer in units of rad/s2
