A particle moves along one dimension with a constant acceleration of 4.50 m/s over a time interval. At the end of this interval it has reached a velocity of 12.6 m/s. (a) If its original velocity is 6.30 m/s, what is its displacement (in m) during the time interval? E (b) What is the distance it travels (in m) during this interval? E (c) A second particle moves in one dimension, also with a constant acceleration of 4.50 m/s2 , but over some different time interval. Like the first particle, its velocity at the end of the interval is 12.6 m/s, but its initial velocity is -6.30 m/s. What is the displacement (in m) of the second particle over this interval? E (d) What is the total distance traveled (in m) by the second particle in part (c), during the interval in part (c)? E
