A 5 kg mass is attached to a spring. The mass is compressed fully to the left and released from rest. The mass displays simple harmonic motion with a period of 3 s and a maximum speed of 0.4 m/s. Assume the spring is massless and neglect friction and air resistance.

a. Determine ω

b. What is the amplitude of the oscillations?

c. What is the initial phase (in radians) of the oscillator?

d. What is the spring constant?
