TA: Tomoyuki Nakayama February 15 th – February 16 th , 2010 PHY 2048: Physics 1 with Calculus, Spring 2010 Review: Chapter 8.1-8.8 The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it sure that you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter. ________________________________________________________________________________ A. Work-Energy Theorem 1. Write down the work-energy theorem in two ways. 2. A figure on the right shows a mass m attached to a string of negligible mass. What initial velocity do you need to give at the lowest point for the mass to take a circular path? 3. Two blocks of masses M = 2.0 kg and 2M are connected to a spring of spring constant k = 150 N/m. The horizontal surface is frictionless. The blocks are released from rest with the spring relaxed. What maximum distance does the hanging block fall before it momentarily stops? B. Potential Energy Function 1. The figure on the right shows a plot of potential energy U versus position x of 1-kg particle that can travel only along an x axis, where U A
