Chapter 14.2, Problem 14.2TYU

A glider is attached to a spring as shown in Fig. 14.13. If the glider is moved to x = 0.10 m and released from rest at time t = 0, it will oscillate with amplitude A = 0.10 m and phase angle ϕ = 0. (a) Suppose instead that at t = 0 the glider is at x = 0.10 m and is moving to the right in Fig. 14.13. In this situation is the amplitude greater than, less than, or equal to 0.10 m? Is the phase angle greater than, less than, or equal to zero? (b) Suppose instead that at t = 0 the glider is at x = 0.10 m and is moving to the left in Fig. 14.13. In this situation is the amplitude greater than, less than, or equal to 0.10 m? Is the phase angle greater than, less than, or equal to zero?
