If you fall out of an airplane, your 0-60 will be about 2-3/4 seconds, discounting wind resistance.

Proof?

  v = 60 mph = 27 m/s
  a = 9.81 m / s2

  v = at
  t = v / a = 27 m/s  /  9.81 m/s2 = 2.75 s

As Foghorn Leghorn once said, "You can argue with me, boy, but you can't argue with the immutable laws of physics."
