AP Physics Multiple Choice Practice - Oscillations 1. A mass m, attached to a horizontal massless sp less spring with spring constant k, is set into simple harmonic motion equilibrium position? it's maximum displacement from its equilibrium position is A. What is the mass s speed us it passes throyou. 2. A mass m is attached to a spring with a spring constant k. If the mass is set into simple harmonic motion by displacement d from its equilibrium position, what would be the speed, v, of the mass when it returns to the equilibrium position? (A) V=, md K ( B) v= 1 m ( C ) V = 1 ( D ) v= d / k mig 3. Which of the following is true for a system consisting of a mass oscillating on the end of an ideal spring?

(C) The maximum potential tential energy is achieved when the mass passes through its equilibrium position. D) The maximum kinetic energy and maximum potential energy are equal, but occur at different times. Questions 4-5: A block oscillates without friction on the end of a spring as shown. The minimum and maximum lengths of the spring as it oscillates are, respectively, Xmin and Xmax.
