d=v^2/(32) sin2theta

Where d is measured in feet and v in feet per second.

An outfielder throws the ball at a speed of 75 miles per hour to the catcher who is 200 feet away. At what angle of elevation was the ball thrown?

200 = 75^2/2 sin^2 Ø

400/5625 = sin^2 Ø

sin Ø = √(400/5625) = 20/75 = 1/3

Ø = 19.5°
