... Newton's Laws are fundamental in that they explain the causes of motion of (relatively) large, solid masses. These laws involve the relationship of forces and motion, particularly (a) rest, (b) constant velocity, (c) constant acceleration. For our purposes, forces in mechanics have only 4 sources: ...

... Example 5-5: Two boxes and a pulley. Two boxes are connected by a cord running over a pulley. The coefficient of kinetic friction between box A and the table is 0.20. We ignore the mass of the cord and pulley and any friction in the pulley, which means we can assume that a force applied to one end o ...
