A50.0-g super ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. a
high-speed camera records this event. if the ball is in contact with the wall for 3.50 ms, what is the
magnitude of the average acceleration of the ball during this time interval?

Explanation:

Average acceleration is change in velocity over time.

a = Δv / Δt

a = (22.0 m/s − (-25.0 m/s)) / 0.00350 s

a = 13,400 m/s²

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.
