1. Accelerated Motion and Changes in Direction A body moves with a constant acceleration of 4.00 reaching a final velocity of 12.0m. a. If this acceleration doubled its initial speed without changing its direction what was its displacement during the motion? b. What distance was covered by the motion in part a? c. If this acceleration doubled its initial speed and changed its direction what was its displacement during the motion? d. What distance was covered by the motion in part c? (Hint: the answer should be different from that of b, if you remain stuck I recommend you model the motion using a graph of velocity-time)
