An object moves with constant acceleration 4.00 m/s^2 and over a time interval reaches a final velocity of 12.0 m/s.
(a) If its initial velocity is 6.00 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 -6.00 m/s what is its displacement during the time interval?
(d) What is the total distance it travels during the interval in part (c)?
