## Homework Statement

An air-track glider attached to a spring oscillates with a period of 1.5s. At t = 0s the glider is 5.0 cm left of the equilibrium position and moving to the right at 36.3 cm/s.

What is the phase constant, [tex]\Phi[/tex]

_{0}?

## Homework Equations

x = Acos ([tex]\varpi[/tex]t + [tex]\phi[/tex]

_{0}) {1}

V

_{x}= -V

_{max}([tex]\varpi[/tex]t + [tex]\phi[/tex]

_{0}) {2}

## The Attempt at a Solution

I tried to rearrange equation two for the phase constant, but I am missing A (amplitude). I have tried using v

_{max}= [tex]\varpi[/tex] A but that only works with maximum velocity which I do not have. Maybe I am not seeing something clearly. Can anyone help me out please?
