Sooo i was wondering... Can something that has been dropped from a higj enough hight eventually break the sound barrier. Well, since we know that the gravitational acceleration is approximately 10 m/s^2 and that the speed of sound is approximately 330 m/s i pluged it into the acceleration formula: a=dv/t 10=330/t 10t=330 t=33 s So that told me that something has to fall 33 s to reach the speed of sound. Now that i know that it needs 33 s im going to plug it into this formula: s=(at^2)/2 s=(10*33^2)/2 s=5*33^2 s=5445m So i think i calculated the hight from which something has to be dropped to reach the speed of sound but i need you guys to tell me iff this is actually correct. Sooo if you have time please answer ;) ps. english is not my native language so please excuse my ridiculously bad grammar.
