Transcribed Image Text:
Two identical spheres with masses M = 5 kg and radii R = 5 cm are attached to opposite ends of a thin L = 6R = 30 cm long horizontal rod of mass m = 1 kg. The system has a pin at the center of the rod and can rotate around it in vertical plane, as seen in the figure. At some point you push the sphere on the right with a force of √3 N and the system starts to rotate. F 60⁰ a) What is the rotational (moment of) inertia of the system around its rotation axis? b) Identify all the forces acting on the system and determine the net (total) torque of the system. Specify the direction of the final motion (CCW or CW). c) Find the initial angular acceleration of the system.
