(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 1.5s AT t= 0s the glider is 5.0 cm left of the equilibrium position and moving to the right at 36.3 cm/s

so from what the question i have determined that T = 1.5s x= -0.05m V_x = 0.363m/s

t = 0

Find the phase constant

2. Relevant equations

using these numbers i sub them into the equations for x(t) = Acos( [tex]\omega[/tex]t + [tex]\varphi[/tex]) where [tex]\varphi[/tex] is the phase. -[tex]\omega[/tex]Asin( [tex]\omega[/tex]t + [tex]\varphi[/tex]) where [tex]\varphi[/tex] is the phase. and for

[tex]\omega[/tex] i sub in 2pi / T

3. The attempt at a solution

so after i sub them i solve for [tex]\varphi[/tex], in each equation then i make them equal each other in an attempt to solve for A. however then i dont know what to do. i end up with a mess of inverse sin and cosines ... Am i going about this the right way? if not can some one nudge me in the right direction?
