A horizontal spring with a spring constant of 26.4N/m lies on a frictionless surface, and is attached at one end to the wall. A 150g apple is permanently attached to the other end of the spring. The spring is stretched by 3.75cm, and given initial velocity of 23.0cm/s toward equilibrium as it is released.

Assume the position equation motion; x=A cos (omega t + phi)

1. Find the phase shift for the equation of motion in radians.

2. Find the 2nd time, in seconds that the apple will pass the equilibrium point of the spring.

3. Find amplitude
