No harm intended, just a friendly physics comment. I’m not trying to “own” anyone, just reminding and educating.

Standard motion formula from calculus/kinetics section of physics.
x(t) = x0 + v0*t + (a*t^2)/2. Set initial position to 5 ft, initial velocity to 0 ft/s, acceleration to -32.2 ft/s^2, and x(t) = 0. Solve this for t and you see that dropping an object from 5 feet (even accounting for acceleration), the phone will hit the ground in just over half a second. Of course we can nitpick over air resistance, but seeing as how we are nowhere near reaching terminal velocity, I think we can likely ignore any frictional effects of air.

: I always thought it was more fun to play games on my Original Droid. The keyboard was perfect!

And it has to accelerate, where’s your formula sir?
