What is the 0-60mph time of an aircraft carrier catapult?
According to Wikipedia https://en.wikipedia.org/wiki/Aircraft_catapult an American carrier type Kitty Hawk has a catapult capable of accelerating a mass of 35000 kg to 139 knots (71,51 m/s), and the system's stroke is 76 m.
From the terminal speed and the stroke, a simple calculation gives a mean acceleration of 33,64 m/s/s. Hence, and assuming the acceleration constant along the stroke, the time needed to reach 60 mph = 26,81 m/s is
t=v/a => t=26,81/33.64 => t=0,796 seconds...
