1. The problem statement, all variables and given/known data An air-track glider attached to a spring oscillates with a period of 1.50 s. At t=0s the glider is 4.50 cm left of the equilibrium position and moving to the right at 32.6 cm/s.find the phase constant. 2. Relevant equations w=2pi/t=2pi/1.5=4.189 x=Acos(wt+phi) v=-awsin(wt+phi) 3. The attempt at a solution i tried a systems of equations approach with time equals 0, so the w part drops out, and i keep getting the wrong answer. is this the right approach?
