Constant accleration problem

  1. Jun 18, 2011 #1
    1. The problem statement, all variables and given/known data

    A baseball traveling horizontally at 41m/s is hit by a baseball bat, causing its velocity to become 47 m/s [N]. The ball is in contact with the bat for 1.9 ms, and undergoes constant acceleration during this interval. What is that acceleration?


    2. Relevant equations

    V2 = v1 + a(delta t)


    3. The attempt at a solution
    41= 47 + (a)(0.0019) ?? is this right?

    V1 and V2 look interchanged. You need to consider the proper signs on them as well.
