A ball is thrown straight upward and then returns to the earth, Does the acceleration change during this motion?
A) The acceleration first increases and then decreases
B) The acceleration never changes during the motion
C) The acceleration first points down then up
D) At the high point, the acceleration is zero

This is probably very simple. Im stuck between B and D

acceleration is constant . At the high point the velocity becomes zero but that doesn't mean that there isn't an acceleration.
