HELP! Distance apart question

  1. Sep 20, 2012 #1
    HELP!! I have no clue how to figure out how far apart they are!!! How would I figure out how far the 2 soccer players are?


    Two soccer players, Sherman and Malissa , begin running from approximately the same point at the same time. Sherman runs in easterly direction at 4.00 m/s, while Malissa takes off in a direction 60.0˚ north of east (i.e. [N 30.0˚ E]) at 5.40 m/s.
    (a) How long is it before they are 25.0 m apart?
    (b) How far apart are they after 4.00 s?

    Find the position vector of both the player at any instant. Then the the displacement vector at any instant will be the difference in the position vectors.

    Show the position of the two players at any time.Then find the modulus of the vector difference between their position.
