(1 point) Balls 1 and 2 are each thrown horizontally from the respective heights above level ground (ball
1 is thrown at a lower height than ball 2), and ball 2 has a smaller initial velocity after leaving the
thrower's hand. If air resistance is negligible, how do the accelerations of the balls and the times it takes
them to hit the ground compare?
