An athlete throws a ball straight upward with an initial speed of 12 meters per second. The ball

reaches a maximum height and then falls back down toward the athlete. What are the

magnitudes of the velocity and acceleration of the ball at its maximum height?

O A. velocity = 0 m/s; acceleration = 0 m/s

B. velocity = 0 m/s, acceleration = 9.8 m/s

O C. velocity = 12 m/s; acceleration = 0 m/s

OD. velocity = 12 m/s; acceleration = 9.8 m/s
