    A Couple Deceleration Questions

    First count the distance that it travels in one second (before the brake is applied). Then using the given acceleration find the distance it travels while decelerating from 95 to 0, you should use the equation: final v squared minus initial v squared is 2ad where a is acceleration and d is...
