A frog is thrown horizontally from a 20 meter tall hill with an initial speed of 4 m/s. How far forward will it travel in the first second of its flight? You can ignore air
resistance.
4 m
5 m
80 m
2 m
8 m
40 m

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.
