4. A 60-kg person runs with a velocity of 5 m/s along a tangent to a stationary circular platform, of radius 3 m and mass 100 kg, and jumps on (see Figure). The platform (a disk) can rotate about a vertical axis. Find: (a) the angular velocity after the person jumps on; (b) the loss in mechanical energy. (Moment of inertia of the disc about an axis passing through its center of mass is lo = MR/2) 4.
