Question

One of the fastest recorded pitches in major-league baseball, thrown by Billy Wagner in 2003, was clocked at 101.0 mi/h (Fig. P3.22). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away

Answer 1

First lets change to feet per second:
(101.0m/h)(1h/3600sec)( 5280ft/1m) = 148.133ft/sec

Horizontal:
D = rt
t = D/r
t = 60.5/148.133
t = 0.408417sec

Vertical: [acceleration of gravity = 32ft/sec^2]
s = (1/2)gt^2
s = (1/2)(32)(0.408417)^2
s = 2.669feet
