Kinematics one dimension. help

    kinematics one dimension. help!!

    hi i've had a lot of trouble with this problem and i hope someone can help me.

    Car B starts from rest and accelerates at 2.00m/s^2 along a straight road. Car A starts from rest at the same instant 20.0 m behind car B and accelerates 3.00 m/s^2. How far must car A move in order to catch car B? What will be the speeds of car A and car B?

    Can someone explain this problem to me and show me how to do it? I am ver confused. Thanks!!

    I think this should be in the homework section.

    You can determine how far each car travels from its starting position in a given time. Now add 20 m to car A then ask yourself when will the two distances be the same.
