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

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
