a particle M oscillators (that is, moves back and forth) in a straight line along the horizontal axis. the position of M is given by:
s(t) = 4 + 2 sin(2t)
(1) Find the velocity (v) and acceleration (a) functions.
(2) Find the initial position, initial velocity and initial acceleration of P.
(3) On graph paper (if not using a computer), accurately plot the graphs for (v), (a) and
(s). Show the time on the horizontal axis in terms of .

velocity=derivative of position
= 4cos(2t)
acceleration is derivative of velocity
= 8sin(2t)
