Based on that equation, it looks like they're figuring a = 20ft/s^2, or
t = 0.05v (v in ft/s).

160 mph = (160)(1.467 ft/s) = 234.67 ft/s.

So t = (0.05)(234.67) = 11-12 seconds.

...which is a plenty long for your life to flash before your eyes.

good times,

If Haydn had patented "a symphony, characterised by that sound is produced
