A 0.25 kg mass is attached to the end of a spring connected horizontally to a wall. The mass is displaced 8.5 cm, then released, and it undergoes SHM. The spring constant is 1.4 x 10^2 N/m. Assume the amplitude of oscillation remains constant.

a.) How far does the mass move in the first five cycles?

b.) Compare the phase after 2.5 cycles with the initial phase.

c.) What is the period of oscillation of the mass-spring system?
