Check the three scenarios that have balanced forces. a Qamar rests at the top of Stone Mountain and enjoys the view.

B A tow truck tries and fails to pull a car out of a ditch. Neither the car nor the tow truck move.

C Malik throws a baseball from first base to second.

D Nur is ice skating and glides across the ice in a straight line and a constant speed.

E Samya and Jordan run into each other in bumper cars. They bounce off each other and go in new directions

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.
