Question
(d) During which segments is the particle moving with constant velocity? During which of these segments is the particle moving the fastest? [1]
(e) During which segments is the particle moving with constant acceleration? During which of these segments is the particle accelerating the fastest? [1]
(f) What is the magnitude and direction of the particle%u2019s average acceleration from A to C? Has the particle sped up or slowed down during this segment? [1]
(g) During which segment(s), if any, is the particle speeding up, and in what direction(s) isthe acceleration? [1]
