Intro physics question

  1. Sep 6, 2011 #1
    You are driving along the New York State Thruway in
    a line of cars all travelling at a constant speed of 106.8 km/hr.
    The car in front of you applies its brakes for maximum accelera-
    tion. You then apply your brakes to achieve the same maximum
    acceleration after only a 1 s delay due to reaction time. What
    distance behind the car in front of you must you be to avoid a
    collision?

    When I want to make MY car accelerate, I hit the gas. I find it very weird that you hit the brakes to accelerate.
