As part of a carnival game, a m, = 0.478 kg ball is thrown at a stack of 16.3 cm tall, m, = 0.363 kg objects and hits with a perfectly horizontal velocity of Uhi = 13.1 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of Ubf = 4.60 m/s in the same direction, the topmost object has an angular velocity of @, = 1.63 rad/s about its center of mass, and all the remaining objects are undisturbed. Assume that the ball is not rotating and that the effect of the torque due to gravity during the collision is negligible. If the object's center of mass is located r = 11.4 cm below the point where the ball hits, what is the moment of inertia I, of the object about its center of mass? I, = 0.284 kg-m2 What is the center of mass velocity vo.cm of the tall object immediately after it is struck? Vo,cm m/s Incorrect
