An object of mass 6.8 kg is attached to an ideal spring of spring constant 1720 N/m. The object is set into simple harmonic motion, with an initial velocity of 4.1 m/s and an initial displacement of 0.11 m.

a) Find the amplitude of oscillation. b) Find the maximum speed of the oscillating object. c) Find the acceleration of the object at position x = 0.11 m. d) How long does it take the object to go from equilibrium position to maximum displacement from equilibrium?
