At a certain time a particle had a speed of 86 m/s in the positive x direction, and 5.2 s later its speed was 25 m/s in the opposite direction. What was the average acceleration of the particle during this 5.2 s interval?

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

i need the answer to this too but idk it ; -;

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.
