Finding time given acceleration and velocity

  1. Jan 27, 2007 #1
    I am having troubles with a physics question. I can't figure out what formula to use to solve the following question:

    Particle A passes a point with an initial velocity of 14.3 m/s and an acceleration of 4.15 m/x^2. Particle B has a 46 m head start at 7.85 m/s with an acceleration of 2.68 m/s^2. At what time will A pass B? Answer in units of s.

    Any suggestions.

    Have you come across the kinematic equations for constant acceleration? Which one of these do you think you should use, considering the variables you are given?
