Chapter 9, Problem 19CQ

Monica stands at the edge of a circular platform that is slowly rotating on a frictionless axle. She then walks toward the opposite edge, passing through the platform’s center. Describe the motion of the platform as Monica makes her trip.

A solid sphere with radius 0.11 m and mass 2.8 kg rolls without slipping around a track that has been bent into avertical circle of radius R = 2 m. (Note that the center of mass of the ball moves in a circle with a radius (R − r),as shown by the dashed line in the figure). At the top of the track, the ball moves with speed 7.6 m/s. What is thespeed of the ball at the bottom of the track?
A simple and practical understanding of conservation of momentum problems is given by the following: When a figure skater makes a jump, he increases his rotation speed by pulling together his arms and legs. This reduces his rotational inertia causing him to spin faster. If the initial spin rate of a figure skater is 1 RPM and he decreases his rotational inertia by half during the spin, what is his final spin rate?
As shown represents a small, flat puck with mass m = 2.40 kg sliding on a frictionless, horizontal surface. It is held in a circular orbit about a fixed axis by a rod with negligible mass and length R = 1.50 m, pivoted at one end. Initially, the puck has a speed of υ = 5.00 m/s. A 1.30-kg ball of putty is dropped vertically onto the puck from a small distance above it and immediately sticks to the puck. (a) What is the new period of rotation? (b) Is the angular momentum of the puck–putty system about the axis of rotation constant in this process? (c) Is the momentum of the system constant in the process of the putty sticking to the puck? (d) Is the mechanical energy of the system constant in the process?
