Question

Ball A is dropped from the top of a building. One second later, ball B is dropped from the same building. Neglect air resistance. As time progresses, the difference in their speeds​

Answer 1

Answer:

Originally Answered: Ball B is dropped down 1 second after the Ball A is dropped . As the time goes the distance between the ball decreases, increases or does not change?

Assuming there is no air resistance or air resistance is equal, the distance increases. This is because despite them having identical accelerations, their speeds will always have a fixed difference due to Ball A having been accelerating for a longer period of time by 1 second. This means the distance between the 2 balls will constantly increase by their distance in speed. Their difference in speed is 9.8 m/s if the balls were dropped near the Earth’s surface. Therefore every second the balls would be 9.8 meters further apart.

If there is a terminal velocity for the balls, once they reach that velocity the distance between the two will be constant.
