Which of the statements are true about the collision of two objects with different masses based on Newton's laws of motion?
A. Each object experiences an equal and opposite force.
B. The more massive object will exert a greater force on the less massive object.
Each object will accelerate in an opposite direction from the other but at a
different rate.
D. The less massive object will accelerate due to the force of the collision, but the
more massive object will not.

A. TRUE

B. TRUE

C. It depends on the mass of both the objects

D. TRUE

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
