A simple Harmonic oscillator begins its motion from maximum positive displacement when a certain clock reads t=0.00s. The period of the simple harmonis oscillator is 2.00 s. When the given clock reads time t= 0.206s, the velocity of the oscillator is -.314 m/s. find the position of the oscillator when t= 5.00s.
