Runner A is running at a constant rate of 2.3 m/s when he passes runner B who is stationary. Runner A continues running at a constant pace, and Runner B begins to run 4 seconds after Runner A just passes him. If Runner B is accelerating at a rate of .5 m/s^2, how long will it take Runner B to catch up?
