projectile motion. with baseball falling vertically. [help plz]?

Question

A baseball was clocked at 100.8 mi/h. If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate of 60 ft away?

Answer 1

1 mph = 1.47 ft/sec
g=32 ft/sec^2

the time to travel 60 ft at 100.8 mph is
60=100.8*1.47*t
solve for t
us t in the following equation to compute the drop
y=-.5*32*t^2
