An object moves with constant acceleration 4.40 m/s² and over a time interval reaches a final velocity of 11.4 m/s.
(a) If its original velocity is 5.70 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 -5.70 m/s, what is its displacement during this interval?

(d) What is the total distance it travels during the interval in part (c)?
