  1. Aug 7, 2011 #1
    1. an 85kg jogger is heading due east at a speed of 3m/s. A 55kg jogger is heading 39degree north of east at a speed of 3m/s. Find the magnitude and direction of the sum of the momenta of the two joggers.

    I’m sure you must have some idea about the question. If this is a homework question, then isn’t this subject covered by your instructor and supported by course materials? This question is talking about vector addition—in this case, the addition of 2 momentum vectors. Have you covered vector addition? Momentum? Do some reading and give it a try, and then come back with any questions you might have.
