Homework Help: Physics. baseball dropping

  1. Sep 17, 2009 #1
    1. The problem statement, all variables and given/known data

    A major-league pitcher can throw a baseball in excess of 46.8 m/s. If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches the catcher who is 15.7 m away from the point of release?

    2. Relevant equations

    3. The attempt at a solution

    i first found time using v=d/t
    so 46.8 = 15.7/ t
    t= 0.33

    then i used the formula x=x_0 +v_0*t
    so x=15.7+46.8*0.33
    x= 31.14

    You have the time, but you use the wrong distance formula. Remember that gravity is constantly accelerating the ball downwards.

    ok y=y_0 + v_0*t-g/2*t^2
