Yeah the correct answer was -1.29 rad. Thanks for the help

Yes they are, and 2pi-phi = 4.99 which I already tried. I'm stumped here

My mistake, I left out a step. I thought the phase shift was greater than 1.29 rad, so i took the angle between that and 1/2pi (0.28 rad). I added that number to 3pi/2 for a phase shift of 4.99 rad, which is still wrong.

Homework Statement A 590.0 g mass oscillates with an amplitude of 11.4 cm on a spring whose spring constant is 27.7 N/m. At t=0.00 s the mass is 3.14 cm to the right of the equilibrium position and moving to the right. Homework Equations x(t)=Acos(Wt + phi) The Attempt at a Solution...
