I'm not quite sure on what I did wrong. Can anyone please help me with this?(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

An air-track glider attached to a spring oscillates with a period of 1.50sec . At the glider is 4.60cm left of the equilibrium position and moving to the right at 33.4cm/s.

What is the phase constant , if the equation of the oscillator is taken to be ? Give an answer in the range -pi < Q < pi.

2. Relevant equations

phase constant = Q

Amplitude = A

angular frequency = w

x(t) = Acos(wt+Q)

v(t) = -Awsin(wt + Q)

w = (2pi)/period

3. The attempt at a solution

4.6 = Acos(Q)

33.4 = -Awsint(Q)

Q = atan(.334/(.046*(2pi/1.5))
