TA: Tomoyuki Nakayama Monday, February 21, 2011 PHY 2048: Physics 1 with Calculus, Spring 2011 Review: Chapter 8.1-9.3 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 Energy In the figure, the string is L = 1.5 m long, has a ball attached to one end, and is fixed at its other end. A fixed peg is at point P . Released from rest, the ball swings down until the string catches on the peg; then the ball swings up around the peg. If the ball is to swing completely around the peg, what value must distance d exceed? B. System of Multiple Particles A boy of mass 50 kg and girl, who is lighter, are in a 30 kg canoe. When the canoe is at rest in placid water, they exchange seats, which are 3.0 m apart and symmetrically located with respect to the canoe’s center. If the canoe moves 0.2 m relative to water, what is the girl’s mass?
