After a jump, a skydiver reaches terminal speed in 10 seconds. Does he gain more speed during the first second of fall or the ninth second of fall? which of these two seconds (1st or 9th) will he fall the greater distance?

  • physics -

    According to the drag equation,

    a = g - k/m v^2

    and the diver approaches terminal velocity asymptotically. Sounds to me like he gains speed more slowly the longer he falls.

    A little web searching should clear it up.
