HELP PLEASE A basketball has a potential energy of 60 J when it is 2 meters above the ground. What is its potential energy when it is 8 meters above the ground? Justify your answer, using proportionality.

The basketball fact->Has a potential energy of 60 J when it is 2 meters above the ground.

Now we need a formula for it.

^60 J divided by 2= 30 J

Now that we have a formula we break down the second part

The basket ball new question->What is its potential energy when it is 8 meters above the ground?

We set up our old equation but with new parts

30 J x 8= 240 J

what is the question?

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.
