Question

Consider a ball thrown straight upward. It moves up, changes direction, and falls back down. Ignore air resistance. What is the acceleration of the ball on the way up? What is the acceleration when it reaches its top point? What is the acceleration on the way down? a) Acceleration of the ball on the way up is -9.8 m/s^2, acceleration when it reaches its top point is 0 m/s^2, and acceleration on the way down is 9.8 m/s^2. b) Acceleration of the ball on the way up is -9.8 m/s^2, acceleration when it reaches its top point is 0 m/s^2, and acceleration on the way down is -9.8 m/s^2. c) Acceleration of the ball on the way up is 9.8 m/s^2, acceleration when it reaches its top point is 0 m/s^2, and acceleration on the way down is 0 m/s^2.
