A ball is rolling down a hill. At one point near the top of the hill, it’s velocity is 2 m/s. Further down the hill, it’s velocity is 9 m/s what is tringlev?

Explanation:

The change in velocity is the final velocity minus the initial velocity.

Δv = v − v₀

Δv = 9 m/s − 2 m/s

Δv = 7 m/s

real, smaller and upside-down.   so the answer should be b.

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.
