An object moves with constant acceleration 3.60 m/s2 and over a time interval reaches a final velocity of 12.4 m/s. (a) If its initial velocity is 6.2 m/s, what is its displacement during the time interval? (b) What is the distance it travels during this interval? (c) If its initial velocity is −6.2 m/s, what is its displacement during the time interval? (d) What is the total distance it travels during the interval in part (c)? I have already solve parts a, b, and c. For some reason d is tricking me though. is total distance different than distance traveled in part b?? a-15.99m b-15.99m c-15.93 d-?
