As the baseballs fall, neglecting air resistance, both of them experience the same acceleration due to gravity ((9.8 , \text{m/s}^2)). Since they start falling at different times, the difference in their speeds will increase over time. This is because the first baseball has a head start, so it will be moving faster than the second baseball throughout their descent. The velocity of the first baseball will be greater than the velocity of the second baseball, and this velocity difference will continue to increase until they reach the ground. Therefore, the difference between the speeds of the two baseballs will increase as they fall.
