Baseball pitcher

  1. Sep 24, 2006 #1
    Alright, I am really stumped. Was wondering if somebody could point me in the right direction, because I am lost.

    "The fastest recorded pitch in Major League Baseball, thrown by Nolan Ryan in 1974, was clocked at 100.8mph (45.06163m/s). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 18.3m away?

    This is a projectile motion problem. The baseball has two components to its velocity as it flies through the air: a horizontal component that stays the same (since there are no forces that act horizontally) and a vertical component that changes (because of the force of gravity). You are given the horizontal velocity (45.06 m/s) and the horizontal distance (18.3 m). From this, compute the time. Then, compute how far the baseball fell vertically in that same time.

    100.8 mph is the fastest pitch you say? That's complete shuttlecock! Just the other day, I saw a Yankee closer throw a high heater at 103mph.
