11.27. Set Up: After one period the motion repeats. Solve: (a) (b) (c) 11.28. Set Up: Velocity and position are related by Acceleration and position are related by The maximum speed is at and the maximum magnitude of acceleration is at Solve: (a) For and (b) The speed is (c) For (d) (e) 11.29. Set Up: Velocity, position and total energy are related by The maximum speed is at Solve: (a) (b) so (c) For and Reflect: When the system has both kinetic and elastic potential energy. When the energy is all elastic potential energy and when the energy is all kinetic energy. 11.30. Set Up: Energy conservation gives At and Solve: (a) gives and (b) so (c) so Or, we can use to get the same result apart a small round off effect. 11.31. Set Up: Velocity, position and total energy are related by Acceleration and position are related by The maximum magnitude of acceleration is at Solve: (a) and A 5 Å 2 E k 5 Å 2 1 22.3 J 2 315 N / m 5 0.376 m.
