Front

A ball is thrown and follows a parabolic path. Air friction is negligible. Point Q is the highest point. Points P and R are the same height. Compare speeds at points P, Q, and R.

Back

v_Q < v_R = v_P

Front

A ball is thrown and follows the parabolic path shown above. Air friction is negligible. Point Q is the highest point on the path. Points P and R are the same height above the ground. Which of the following diagrams best shows the direction of the acceleration of the ball at point P?
