A football is thrown in a parabolic path. At which point of the path, if any, is the acceleration parallel to the velocity, and at which point is it perpendicular to the velocity?
Options:
Answer:
B
Solution:
The acceleration is vertically downward throughout. The velocity is horizontal only at the top, so the acceleration is perpendicular to the velocity there; the velocity is never vertically downward everywhere else except nowhere along the path, so the two are never parallel. Option B.
