TA: Tomoyuki Nakayama Monday, November 22, 2010 PHY 2048: Physics 1 with Calculus, Fall 2010 Review: Chapter 15.1-15.9 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. Simple Harmonic Motion A 2-kg block on an incline is attached to a spring with a spring constant of 100 N/m . The incline is frictionless and it makes an angle of 45º to the horizontal. The block is pulled down slightly from the equilibrium point and released. What is the period of the motion? B. Pendulums The pendulum shown below right consists of a uniform disk with radius r = 20.0 cm and mass m = 1.2 kg attached to a uniform rod with length L = 40 cm and mass M = 0.8 kg. What is the period of the motion?
