A 85.7 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.59 rad/s. A monkey drops a 8.67 kg bunch of bananas vertically onto the platform. They hit the platform at of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 20.7 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with...

A solid, uniform disk of mass 1.00 kg and radius .250m rotates with initial angular velocity of +26.3 rads/s about a frictionless vertical spindle through the center of the disk. A flat rectangular steel bar of mass 0.850 kg, length 0.400m, and width 0.050 M is dropped onto the disk so that the spindle passes through the center of the bar and is perpendicular to the plane of the bar. Assuming that there are no external torques on the system...
