A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant
shown, the ball is at point B. Point C represents the highest position of the ball above the ground.
Which statement is true concerning the ball when it is at C, the highest point in its trajectory?
The horizontal and vertical components of the ball's velocity are equal.
The ball's velocity is not zero, but its acceleration is zero.
The ball's velocity is perpendicular to its acceleration.
The ball's velocity is zero, but its acceleration is not zero.
The ball's velocity and acceleration are both zero.
