TA: Tomoyuki Nakayama Monday, February 28, 2011 PHY 2048: Physics 1 with Calculus, Spring 2011 Review: Chapter 9.4-10.10 The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A. Conservation of Momentum In the figure below right, block 1 of mass 3.0 kg is moving rightward at 10 m/s and block 2 of mass 5.0 kg is at rest. The surface is frictionless, and a spring with a spring constant of 800 N/m is fixed to block 2. When block 1 hits the spring, what is the maximum compression of the spring? B. Rotational Motion A yo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 10 kg box as shown in the figure below. The outer radius R of the device is 0.5 m, and the radius r of the hub is 0.2 m. When a horizontal force of 60 N is applied to the rope wrapped around the outside of the device, the
