**Damon**, Saturday, June 28, 2014 at 3:14pmHow long to fall ?

54 = (1/2) g t^2

108 = 9.81 t^2

t = 3.32 seconds in the air, screaming and wishing for parachute

In 3.32 seconds we went 130 meters at constant horizontal velocity u

130 = t (3.32)

t = 39.2 m/s

so now convert that to miles/hr. (Google). 87.7 miles/hr it says
