Homework Help: Baseball runner asking for velocity to an out

  1. Apr 22, 2013 #1
    1. The problem statement, all variables and given/known data

    A fast base-runner can get from first to second base in 3.45 s. If he leaves first base as the pitcher throws a 90 mi/h fastball the 69-ft distance to the catcher, and if the catcher takes 0.45 s to catch and rethrow the ball, how fast does the catcher have to throw the ball to second base to make an out? Home plate to second base is the diagonal of a square 90 ft on a side.

    2. Relevant equations

    v= vi + at

    3. The attempt at a solution

    Subtracted the .45s to the 3.45s so i can be left with just 3s

    So what has to happen in those 3 seconds?
