The fastest recorded pitch in Major League Baseball was thrown by Nolan Ryan in 1974. If this pitch were thrown horizontally, the ball would fall 0.809 m (2.65 ft) by the time it reached home plate, 18.3 m (60 ft) away.
The acceleration of gravity is 9.81 m/s2 . How fast was Ryanâ€™s pitch? Answer in units of m/s

distance fell= 1/2 g t^2
.809=4.9 t^2 solve for t, the time it was in the air.
howfast=distance/time= 18.3m/time
