Homework Help: A question on momentum.

  1. Jan 16, 2012 #1
    1. A 45kg sprinter runs at 12 m/s for a short distance. What is his momentum?



    2. p=m*v



    3. p= (45kg)(12m/s)
    p= 540


    I'm not sure if I did it right. & am I supposed to include unit(s) after 540? :confused:

    Looks good! Yes, the units should be included. kg⋅m/s
