7) At t= 0, one toy car is set rolling on a straight track with initial position 15.0 cm, initial velocity 23.50 cm/s, and constant acceleration zero. At the same moment, another toy car is set rolling on an adjacent track with initial position 10.0 cm, initial velocity 15.50 cm/s, and constant acceleration 2.4 cm/s². (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? (d) What are their locations at that time?
