At t = 0, one toy car is set rolling on a straight track withinitial position 16.5 cm, initial velocity -3.4 cm/s, and constantacceleration 2.30 cm/s2. At the same moment, another toy car is setrolling on an adjacent track with initial position 9.5 cm, initialvelocity 6.20 cm/s, and constant zero acceleration.
(a) At what time, if any, do the two cars have equal speeds?
(b) At what time(s), if any, do the cars pass each other?
(c) What are their locations at that time?
(d) Explain the difference between question (a) and question (b) asclearly as possible.
