Machanics? taunt? Wow. Now to greater errors. What exactly is a mass of 3m or 5m? And in the answers, since when is force measured in milligrams? Isn't that a mass unit? Something is major wrong in your physics class, this usage is not acceptable: Remember this was the ...

can u tell me what formula i should be using to answer this question? If a stone falls past a bird on a ledge moving at 4 m/s, how fast will the stone be movingjust before it hits the ground below 9 seconds later? A. 92.2 m/s B. 48.2 m/s C. 352.8 m/s D. 36 m/s
