**Question:**A 90 kg woman on roller skates pushes a 35 kg girl, also on roller skates, with a force of 50 N. The magnitude of the force exerted by the girl on the woman is:- ○ 200 N- ○ 100 N- ○ 50 N- ○ 40 N- ○ 38 N- ○ zero**Explanation of Concept:**This question deals with Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When the woman pushes the girl with a force of 50 N, the girl exerts an equal and opposite force of 50 N back on the woman. Therefore, the correct answer is 50 N.

By Newton's third law "For every action in nature is an equal and opposite reaction"Force exerted by woman on girl and force exerted by girl on woman is equal. Answer-) 50 N

It may appear at first glance that Newton's 2nd and 3rd laws are independent claims. This, however, is not true - Newton's 3rd law is simply a consequence of Newton's 2nd law. In this problem, you will prove Newton's 3rd law for the normal contact force between two objects, using only Newton's 2nd law.

Dr. Miller is conducting an experiment. He has a stack of books on a table which is frictionless and flat. He applies a force F on the stack, and finds that it accelerates at 3.0 m/s². He then adds a book to the stack. This is a physics textbook that has a mass of 1.0 kg. He then applies the same force F on the stack and finds that now the stack accelerates at 2.0 m/s². What was the mass of the original stack of books? a) 1.0 kg Ob) 2.0 kg c) 3.0 kg O d) none of the above
