I know the question is simple... but I don't get it. A metal ball is thrown from a tall building V0= 0. When will it reach V=25 m/s? This is my first question, I seem to like physics yet I don't understand anything... accept electricity, but the rest, I don't. I hope I don't annoy anoyone but I really need help because I want to be good at this subject. Thank you in advance!
