Can something dropped break the sound barrier?

  1. May 9, 2016 #1
    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.

    Ohh, thanks i didnt know that, but could my calculations be close or at least partially correct.
