A ball of clay (mass, m) is traveling to the right with a velocity of 10.4 m/s. It collides with a stationary 1) unknown object (mass 3m, effective radius 1 m), and the two objects stick together after the collision. The final angular speed of both objects is F 2 radians/sec in the clockwise direction, and you can assume the unknown object is nailed in place and that there is no friction in this problem. A momentum chart may be...
