Question

At t = 0, one toy car is set rolling on a straight track with initial position 14.5 cm, initial velocity -4.5 cm/s, and constant acceleration 3.00 cm/s2. At the same moment, another toy car is set rolling on an adjacent track with initial position 11.0 cm, initial velocity 5.70 cm/s, and constant zero acceleration.
(d) What are their locations at that time? (If there is only one position, enter NA in the second blank. If there are two positions, enter the smaller position first. If they never pass, enter NA in both blanks.)
