I Example #1 (Zero - Angle) Rolyna climbs to the top of a mountain. She finds a rock on the
mountain and throws it so that it hits the ground 300 meters away from the base of the cliff. If
she is 500 meters above the ground and she throws the rock horizontally, with what velocity does
she throw the rock?

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.

i think the answer is tomato juice? not entirely sure though

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
