Question

Quizplus · Accepted Answer

Since both balls are being dropped from the same height and neglecting air resistance, they will experience the same acceleration due to gravity of 9.8 m/s^2. Therefore, their speeds will increase at the same rate and remain constant relative to each other, meaning the difference in their speeds will remain constant as well.
