  1. Oct 10, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the momentum of a 75 kg freshman moving southward at 3m/s


    2. Relevant equations
    Momentum = mass x velocity


    3. The attempt at a solution
    75 kg x 3 m/s = 225 Units

    Am I correct??

    "Units" is not correct.

    I see what you mean. I believe kg•m/s is the proper unit for momentum. Regardless, I submitted the answer as 225 Units, and the professor counted it correct. lol
