The diagram shows the displacement-time graph for a body performing simple harmonic motion. Suggest in terms of period T the following
(a)    range of time where the velocity and acceleration are in same direction.
(b)    range of time where the velocity and acceleration are in opposite directions
 T 4 < t < T 2 a n d 3 T 4 < t < T ,  0 < t < T 4 a n d T 2 < t < 3 T 4

Solution:
