They don't tell you the angle (measured above horizontal) that the ball was thrown, but you can figure it out. For a ball thrown horizontally, the distance fallen (vertically) is Y = (g/2) t^2 = 17.9 m Since that is also the height of the building, it WAS thrown horizontally. ...

One of the fastest recorded pitches in major-league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (see the figure). 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 ...

A major-league pitcher can throw a ball in excess of 36.2 m/s. If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches a catcher who is 17.0 m away from the point of release? I got -1.08 for the answer but my book is saying its wrong! ...
