In neither case is the accelerationproportional to the position. Neither motion is so smooth asSHM. The ball’s acceleration is very large when it is in contactwith the floor, and the student’s when the dismissal bell rings.Q15.2You can take φπ=, or equally well, =−. At t=0, the particleis at its turning point on the negative side of equilibrium, atxA.Q15.3The two will be equal if and only if the position of the particle
