Chapter , Problem 8

(choose chapter or problem)

You are standing on the edge of a turntable with frictionless bearings that is initially rotating when you catch a ball that is moving in the same direction but faster than you are moving and on a line tangent to the edge of the turntable. Assume you do not move relative to the turntable. (a) Does the angular speed of the turntable increase, decrease, or remain the same during the catch? (b) Does the magnitude of your angular momentum (about the rotation axis of the table) increase, decrease, or remain the same during the catch? (c) How does the balls angular momentum (about the rotation axis of the table) change after the catch? (d) How does the total angular momentum of the system, youtableball (above the rotation axis of the turntable), change after the catch?
