Hi,
I have a question on Newton's second law.
I have a box in which an egg rests inside. Egg is surrounded by some sort of padding. A force is applied to the box. (Force has an x and -y component.
Are my conclutions right?
1) Force act on the box, not on the egg. Applying Newton's second law to the whole system one can get the system's accelertation,
F = (m1 + m2 ) a
2) Net force on the egg = zero. Egg does not move.
3) What does the padding do? Is it to avoid the egg moving at the beginning of the application of the force? At the beginning, due to Newton's third law, egg will move against the applied force and go hit the back of the box. So if I gradually increase the applied force can I avoid the padding?
(4) Force applied in the negative y direction would make it difficult to move the box.
I get confused with my first statement. Technically egg moves with respect to a person out side the box. So the egg shoud have accelerated which means egg shoud be experiencing a force?? How to clear my confusion?
Please pour in your knowledge on this egg problem. I know egg box system is a very common school problem in USA.
Thank You.
