A particle moves along the x axis. It is initially at the position 0.210 m, moving with velocity 0.090 m/s and acceleration -0.340 m/s2. Suppose it moves with constant acceleration for 3.90 s. Next, assume it moves with simple harmonic motion for 3.90 s and x = 0 is its equilibrium position.
(a) Find its position.
(b) Find its velocity at the end of this time interval.
