at the origin, car A starts from rest and accelerates at a rate of 0.9m/s2 and moves to the right. at the instant car A starts, car B passes the origin at a velocity of 28 m/s to the right and immediately slows down at a rate of 0.7m/s2. take right as +X.

A) find the time t at which car A catches up with car B

B) sketch the position vs time graph of car A and car B on the same figure. Label car A and B clearly. (shapes of graphs are most important)
