Suppose a large box with a man inside.He is standing on a side of the box which he calls as the 'floor'.(This immediately indicates that this is an accelerated frame of reference). Also assume there is vacuum inside as well as outside the box. Now he is going to walk over the floor to punch with his fist an adjacent side. And then he did punch the wall. Two questions come into my mind. They are:
- While he is walking the distance on the floor towards the adjacent wall ,would the floor move in opposite direction according to Newton's 3rd law? (like a treadmill?)
2.When he punches the adjacent wall, would the wall move in the direction of punching with he himself getting recoiled away from the wall due to Newtons 3rd law?
It would be great if an explanation is also provided. Also does the law of conservation of momentum got to do anything in this scenario?
