A box is sliding with a speed of 4. 50 m/s on a horizontal surface when, at point p, it encounters a rough section. On the rough section, the coefficient of friction is not constant, but starts at 0. 100 at p and increases linearly with distance past p, reaching a value of 0. 600 at 12. 5 m past point p.
