Homework Help: How to solve the Momentum of a baseball?

  1. Jun 22, 2015 #1
    Question is:
    A .145kg baseball is thrown at 40 m/s (~89.5mph). What is the momentum of the baseball?
    Enter units of momentum as kg m/s

    I have used the following solutions for the question, but the answer I'm submitting is coming back wrong.

    I have entered:
    116 J
    5.8 kgm/s

    The formula I used to solve the question is p=mv p=(.145kg)(40m/s) = 5.8
    Please help...
