A box sits in a wagon. Both are being accelerated uniformly at 3.2 m/s2. The box, which has a weight of 134 N, does not move relative to the wagon. The coefficient of static friction between the box and the wagon's surface is 0.68, while the coefficient of kinetic friction is 0.44. Determine the magnitude of the friction force acting on this box.

Explanation:  c) Solve both problems assuming the truck has four-wheel drive. Question Image. <b>Table 5.1</b> Coefficients of Static and Kinetic Friction ... with the coefficient of static friction on the wrong assumption that the truck box was made of metal. The coefficient of static friction should be that for metal on wood, which is 0.5.
