On a straight stretch track a toy car is set rolling with an initial position of 16.0 cm, an initial velocity of-3.1 cm/s, and a constant acceleration of 2.10 cm/s2. at the same moment, another toy car is set rollingon an adjacent track with an initial position of 11.5 cm, an initial velocity of 5.40 cm/s, and a constantzero 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?
d. what are their locations at that time?
