A race car accelerates from rear at a rage of 7.5 m/s^2 for 4.5s. How fast will it be going at the end of that time?

the answer is c i did the same question so i know that's right!

what is the question because that is not a 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.

its a 5.5 n

glad that
