Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of ?b,f=3.10 m/svb,f=3.10 m/s in the same direction, the topmost object has an angular velocity of ?o=4.03 rad/sωo=4.03 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.
