Q: A tennis ball is launched upward at an angle from starting Point A. Point B is at the top of its parabolic trajectory (the highest position of the ball above the ground), and Point C is when it hits the ground. At which point in its trajectory is the ball's velocity vector changing most rapidly with respect to time?
A		Point A
B		A point between Point A and Point C
C		Point C
D		The change in velocity is the same at any point in the trajectory
