PHYS 2101 : Exam 3 Multiple Choice Questions
Document Summary
Exam #3 multiple choice questions: two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. Just before the ball hits the ground, it is traveling at a speed v. just after it bounces, the ball is moving upward at a speed 0. 75v. Ignore any effects due to air resistance: a quarter is dropped from rest from the fifth floor of a very tall building. The speed of the quarter is v just before striking the ground. Ignore all air resistance effects to determine your answer: 14, 25, 20, 7, 10, two identical cars were involved in a collision at an icy intersection. Car a was stopped at a traffic light. Car b was moving at a speed v when it suffered a perfectly inelastic collision with the back end of car a.
