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
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
Homework 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
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 don't 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?
