What is the maximum acceleration? 1. 0.15625 m/s2 2. 0.963829 m/s 3. 0.0488281 m/s2 4. 0.306796 m/s PNU 5. 1.92766 m/ 6. 6.1685 m/s 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. 54 t (s) y (cm co+ 2 4 5 5+ At what time t in the period shown does the particle achieve its maximum positive ac- celeration? 1. t = 4s 2. t = 2 s 3. t = 3 s 4. None of these; the acceleration is con- stant. 5. t = 1s
