Fundamental question

  1. Aug 28, 2011 #1
    If somthing falls 10 meters (at 10m/s), ignoring air resistance, why does it take 1.4s to land instead of just one?

    I suppose i am simply having a brain fart but this is bothering me....

    Taking g = 10 m/s2, after 1 second the speed will be 10 m/s. But realize that it started from rest, so the average speed during that first second is only 5 m/s, thus it only fell 5 meters during that first second.
