Throwing a baseball example

  1. Sep 20, 2012 #1
    1. The problem statement, all variables and given/known data
    A baseball pitcher throws a fastball horizontally at a speed of 45.0 m/s toward home plate,
    17.1 m away. Ignore air resistance. (a) If the batter’s combined reaction and swing times total
    0.340 s, how long can the batter watch the ball after it has left the pitcher’s hand before
    deciding to swing?


    2. Relevant equations
    I'm thinking x=x(not) + v(not)t + (1/2)at^2


    3. The attempt at a solution
    This equation seems perfect but I can't figure out how to solve for t so that I can find the time it takes the ball to travel the 17.1meters. Then I would take that time and substract the .340s from it and get the answer.

    Thanks!

    Is the horizontal motion accelerated?

    wow...thank you.

    it is not. there for it is simply distance divided by velocity. giving the batter .04 seconds to react.
