# Newton's Third Law and acceleration question

Two wrestlers are pushing each other. Initially the wrestlers are at rest, however the small wrestler starts to move. Now in either cases, which wrestler exerts more force? My professor said that both exert the same amount of force on each other. This is really confusing as if they are applying equal forces on each other, how are they moving. Also say if the larger wrestler exerts 200 N and the smaller exerts 100 N, wouldnt the forces cancel out? If the larger one exerts 200 N, the smaller one then exerts the same force back right (the reaction force). The smaller wrestler exerts 100 N, then the larger would exert back the 100 N ( again Newton's Third Law). Doesnt this cancel out all forces, then how is there motion?

Each man puts a force on the other that pushes them apart. Further, their is a reaction to each force that each applied on one another that pushes them still further apart. There are no forces that push the two men together. Finally, each man will receive twice the force pushing them apart if both apply an equal force on each other.

You might also be confused that $F=ma$ or $a = \frac{F}{m}$. So the acceleration (their motion) is dependent not only on the force, but also on the mass of the object receiving the force. Thus each man depending on their mass will experience different acceleration or a different motion.

see they dont push off each other, they are continually pushing
