  1. Sep 13, 2008 #1
    1. The problem statement, all variables and given/known data
    at t=0, one toy car is set rolling on a straight track with initial position 15 cm, initial velocity -3.50 cm/s, and constant acceleration 2.40 cm/s2. at the same moment, another car is set rolling n an adjacent track with inital position 10 cm, an initial velocity of +5.50 cm/s, and constant acceleration zero. a.) at what time,if anydo 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? e.) explain the difference bt question a and c as clearly as possible

    2. Relevant equations

    xf=xi+ vxit+1/2axt2

    3. The attempt at a solution

    is the above equation the right one to use?
