Going up and coming down through one point, a ball's speeds are
AEqual in magnitude
BLarger when going down
CZero both times
DLarger when going up
Answer & Solution
Correct answer: A. Equal in magnitude
With constant g, v^2 = v0^2 - 2gy gives the same speed at the same height, opposite in direction.
