  1. Sep 24, 2010 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    3. The attempt at a solution

    I got the answer 346, the real answer was 350. Did they just round up?

    Thanks :)

    They rounded up a little, but your answer's not really correct.

    [tex]|v| = \sqrt((300+60cos40)^2+(60 sin40)^2)[/tex]

    This is the way I did it this time. I got 348. Does that seem correct?
