CHAPTER 17

Simple Harmonic Motion

1 . The simple pendulum and a spring-mass system are both displaced from equilibrium (θ and x ), as
shown in the figure, such that they have identical oscillatory time periods (T). The initial
displacements are then doubled to 2θ and 2x , and the masses are again released. What will the new
time periods of each oscillator be?
(A) Pendulum = 2T; mass-spring = 2T
(B) Pendulum = 2T; mass-spring = T
(C) Pendulum = T; mass-spring = 2T
(D) Pendulum = T; mass-spring = T
(E) Pendulum = T; mass-spring = T

2 . A mass of 8 kg oscillates back and forth on a spring of force constant k. A graph of its motion is
shown in the figure. What is the maximum acceleration of the mass?

(A)         

(B)         3π  m/s^2

(C)
