    Box slides with v=4.5m/s down a horizontal surface. At point P, it encounters a rough section. The coefficient of friction is not constant. It begins at .100 at P and increases linearly to .600 at a distance of 12.5m away from P.

    A) Using work-energy theorem, how far does the box slide before it stops?
    B) What is the coefficient of friction when it stops?
    C) How far would it slide if the coefficient of friction remained at .100?
