Question
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
Part A
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.
Use the work-energy theorem to find how far this box slides before stopping.
Express your answer in meters.
