The overall change in velocity is just 20m/s.
answer:
the first one
Explanation:
i think it is this one because 4k is bigger than 2k . also it is asking which one has the lager magnitude so it is the first one
Answer:
D
Explanation:
I just took the test and C was wrong, do not listen to that answer. It is "All of the above"
Since a straight line on a distance time graph implies uniform speed, and falling is an acceleration - a non uniform speed - I woul not expect a straight line.I would expect to get a parabola.This is based on the kinematic equation s=ut+(1/2)at^2. If something is dropped from rest, u = 0; so s = (1/2)at^2Which is, I think, the equation of a parabola.
