A) increases.

C) decreases.
D) increases at first, but then stays constant.
E) decreases at first, but then stays constant.

Question

Quizplus · Accepted Answer

In free fall, without air resistance, both objects will accelerate at the same rate due to gravity (approximately 9.8 m/s^2 on Earth). This means the difference in their speeds remains constant over time, as both are gaining speed at the same rate from the moment they are released.
