At t = 0, one toy car is set rolling on a straight track with initial position 13.5 cm, initial velocity -4.2 cm/s, and constant acceleration 2.60 cm/s2. at the same moment, another toy car is set rolling on an adjacent track with initial position 8.5 cm, initial velocity 5.20 cm/s, and constant zero acceleration.
(a) at what time, if any, do the two cars have equal speeds?
(b) what are their speeds at that time?
(c) at what time(s), if any, do the cars pass each other?
