A rotating horizontal disk with a radius of 2 m and a mass of kg has an initial angular velocity of rad/s. Two objects, each modeled as point masses, are dropped onto the disk’s surface and adhere to it. Object A has a mass of kg and object B has a mass of kg. r1 = 1.2 m and r2 = 1.5 m.  Determine the final angular speed of the system. Express your answer in rad/s.

A uniform bar with a mass of m = kg and a length of L = m is rotating about a vertical axis fixed at its left end. The figure shows the tangential velocity of a point located at a distance of 1/2 L from the rotation axis. t1 = 0, t2 = 2 s, t3 = 5 s, v1 = 5 m/s, v2 = 10 m/s, v3 = 15 m/s, and v4 = 20 m/s. Determine the rotational kinetic energy of the bar at time t = 3 s. Express your answer in joules (J).
