For a satellite to orbit Earth at a constant distance, its centripetal acceleration must be equal to Earth's gravitational acceleration. If a satellite is to orbit with
a constant circular radius of 7,500,000 m, what is the approximate required
velocity of the satellite? (Recall that Earth has a mass of 5.97 x 1024 kg and G
= 6.67 * 10-11 N·m²/kg2)
I need this ASAP pls

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.

because if the tool that you are using is not balanced it there would be false mass.
