A particle moves along the x axis. It is initially at the position 0.330 m, moving with velocity 0.250 m/s and acceleration -0.280 m/s2. Suppose it moves with constant acceleration for 4.60 s.
(a) Find the position of the particle after this time.
_____m
(b) Find its velocity at the end of this time interval.
_____m/s
Next, assume it moves with simple harmonic motion for 4.60 s and x = 0 is its equilibrium position. (Assume that the velocity and acceleration is the same as in parts (a) and (b).)
(c) Find its position.
____m
(d) Find its velocity at the end of this time interval
______m/s
