**drwls**, Thursday, December 3, 2009 at 12:11amThe period of oscillation is

P = 2 pi sqrt(m/k)= 0.898 s

For your other questions, choose a value of the phase angle phi such that

x = 10 cm * sin (2 pi t/P + phi)

and the direction of motion (the sign of dx/dt) is correct.

Fot the x=0 @ t=0 case, phi = pi
