chapter 4 - forces and newton`s laws of motion
... When solving problems involving forces acting on an object, drawing a freebody force diagram is helpful. Example Two people are pushing a stalled car that has a mass of 1850 Kg. One person pushes with a force of 275 newtons and the other with a force of 395 newtons in the same direction. A friction ...
