Two particles A and B start from rest at the origin s=0 and move along a straight line such that a_A=(6t - 3) ft/s^2 and a_B=(12t^2 - 8) ft/s^2, where t is in seconds. Where are the respective reference points of particles A and B? What are the directions of A and B at t= 1.2 s? Where is the position of A at t = 1 s?
