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

A steel ball of mass 0.710 kg is fastened to a cord that is 89.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number i Unit (b) Number i Unit

A 3.10-kg ball, moving to the right at a velocity of +1.43 m/s on a frictionless table, collides head-on with a stationary 8.60-kg ball. Find the final velocities of (a) the 3.10-kg ball and of (b) the 8.60-kg ball if the collision is elastic. (c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic. (a) Number Units (b) Number Units (c) Number Units
