An object moves with constant acceleration 4.20 m/s2 and over a time interval reaches a final velocity of 11.0 m/s.
(a) If its initial velocity is 5.5 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 ?5.5 m/s, what is its displacement during the time interval?
(d) What is the total distance it travels during the interval in part (c)?
