Unformatted text preview: morris (gmm643) – HW 14 – Coker – (56625) 1 This print-out should have 22 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. This assignment covers Chapter 15 on the Simple Harmonic Oscillator. 001 10.0 points A mass attached to a spring oscillates back and forth as indicated in the position vs. time plot below. P x t At point P, the mass has 1. positive velocity and positive accelera- tion. 2. negative velocity and negative accelera- tion. 3. negative velocity and positive accelera- tion. 4. positive velocity and negative accelera- tion. 5. zero velocity but is accelerating (posi- tively or negatively). 6. zero velocity and zero acceleration. 7. positive velocity and zero acceleration. 8. negative velocity and zero acceleration. 002 10.0 points A particle oscillates up and down in simple harmonic motion. Its height y as a function of time t is shown in the diagram. 1 2 3 4 5 5 5 y (cm) t (s) At what time t in the period shown does the particle achieve its maximum positive ac- celeration? 1. None of these; the acceleration is con- stant. 2. t = 2 s 3. t = 1 s 4. t = 3 s 5. t = 4 s 003 (part 1 of 4) 10.0 points A 0 . 5 kg block attached to a spring of force constant 19 . 7 N / m oscillates with an ampli- tude of 7 cm. Find the maximum speed of the block. Answer in units of m / s. 004 (part 2 of 4) 10.0 points Find the speed of the block when it is 3 . 5 cm from the equilibrium position. Answer in units of m / s. 005 (part 3 of 4) 10.0 points Find its acceleration at 3 . 5 cm from the equi- librium position. Answer in units of m / s 2 . 006 (part 4 of 4) 10.0 points Find the time it takes the block to move from x = 0 to x = 3 . 5 cm....
