Rugby player problem

  1. Oct 5, 2010 #1
    1. The problem statement, all variables and given/known data
    two rugby players are running toward each other. They are 37 m apart. if one accelerates from rest at 0.5m/s2 and the other was already moving at 3.1 m/s and maintains his speed,

    a) How long before they tackle each other?

    This question is annoying me so much right now, I found 2 archived solutions to the problem, but they don't explain in enough detail, so I'm just re-posting it so that I may know how to solve it.

    Write out the equation for distance covered by each runner as a function of time. Then write out the equation for separation as a function of those distances ie: s = 37 - (d1(t) + d2(t)). What is the value of s when they collide? Work out t from that.

    Sorry, but I don't understand what you mean by "Function of time", or function of distances, I was attempting to solve it using the linear kinematics equations.
