A) depends on how high they started. B) is the same for eachbullet. C) is greater for the firedbullet. D) is greater for the droppedbullet. E) none of these A bullet is dropped into a river from avery high bridge. At the same time, another bullet is fired from agun, straight down towards the water.

A) depends on how high they started. B) is the same for eachbullet. C) is greater for the firedbullet. D) is greater for the droppedbullet. E) none of these

Explanation / Answer

Well, think about this in this way. When both bullets aregoing downward, the only force acting on them is the force ofgravity, and since you know that FGravity=ma, then mg=ma, since the masses arethe same, we get mg=ma, a=g. Hope this helps.
