A 1.00 kg object attached to a spring of force constant 41.0 N/m oscillates on a horizontal, frictionless track. At t = 0, the object is released from rest at x = -3.00 cm. (That is, the spring is compressed by 3.00 cm.)

Find the displacement, velocity and acceleration as functions of the time t.

my answer:

my legend:

w= angular frequency

&= phase constant

ok, so for displacement: x(t)=Acos(wt+&)

velocity: -wAsin(wt+&)

acceleration: -w^2Acos(wt+&)

A = max displacement, which is .03 m in this case

w= 2(pi)(f)

where f=1/T

where T=2(pi)(square root of m/k)

so solving for all that, i get w=6.41 which i know is right...

so now how do i solve the question?? HOw do i solve each of those equations as a function of something? i have no idea how to do this, i been stuck on this problem forever and i keep getting the wrong answer

thanks
