A professor in a desperate attempt to solve a problem bangs his head on the wall out of frustration.
Now, there are two outcomes possible:
Either the wall will break
The wall will remain intact
Student 1: Outcome 1 is good for professor.
Student 2: Outcome 2 is good for professor, the reason being that if the wall breaks then professor certainly had provided more force than there had been on the wall if professor failed to break the wall. As a direct consequence of Newton's Third Law of Motion, the professor should feels more force hence more pain when he breaks the wall.
Whom according to you is right? If you think Student 1 is right, disprove argument made by Student 2.
