1. The problem statement, all variables and given/known data An air-track glider attached to a spring oscillates with a period of 2.3 s. At t=0 s the glider is 3.09 cm left of the equilibrium position and moving to the right at 35.07 cm/s. What is the phase constant? (in degrees) 2. Relevant equations v0x= -wAsin(ro), x=Acos(ro) 3. The attempt at a solution I divided v0x/x=wtan(ro). I solved for angular speed which was 2.73 rad/s. Now I solved for (ro) by taking tan inverse of (v/-wx). I received 73 as an answer and that's wrong. Would you please help me? Thank you.
