Figure A [[which i tried to recreate below]] is a partial graph of the position function x(t) for a simple harmonic oscillator with an angular frequency of 1.1 rad/s.

[a] ............x(cm)..............

Figure B is a partial graph of the corresponding velocity function v(t).

What is the phase constant of the SHM if the position function x(t) is given the form x = xmcos(ωt + φ)?

φ = ____ rad/s

..... the example in the book had an angular frequency of 1.2 rad/s. & the answer it gave was 1.03 rad/s.

please help! im really stuck on this one.. and it's due tonight.

I don't have a clue on the diagram.
