You drop a stone down a well that is 12.37 m deep. How long is it before you hear the splash? The speed of sound in air is 343 m/s.

  • physics -

    let t1 be the fall time, t2 be the time for sound coming back up. You want t1+t2


    t1:
    12.37=1/2 g (t1)^2 solve for t1
    t2:
    12.37=343*t2 solve for t2
