1) Consider two boxes: box B, with a mass of 3kg, placed on top box A, with a mass of 10kg. If box A is pushed with a force of 70N, what is the force of friction on box B? The coefficients of friction between boxes A and B are µs = 0.7 and µk = 0.4, while friction is negligible between box A and the ground.
2) A 1.5kg box is pushed up a 30o incline with a force F = 20N. If the inclined surface has coefficients of friction µs = 0.4 and µk = 0.2, what is the acceleration on the box?
