Harmonic Motion
find a model for simple harmonic motion d, in centimeters, with respect time t, in seconds, with an intial displacement (t=0) of 0 centimeters, an amplitude of 6 centimeters, and a period of 5 seconds
period
2pi/ omega = 5

omega = 2pi/5

since the intial dissplacement is 0 we will use sin(omega)t

d = 6sin(2pi/5)t

this is where i am stuck, do i solve for d or t? or is the model is the equation?

no, you are done. they just asked for the model. the equation is the model (and d is already solved for)
