Homework Help: Swimmer and River (Relative Velocity)

  1. Oct 29, 2008 #1
    1. The problem statement, all variables and given/known data
    A swimmer is to reach at a point 30 degree upstream on the other side of a river flowing with velocity 5 m/s. The velocity of the swimmer w.r.t. water is [tex]5\sqrt{3}[/tex]. The swimmer should steer at an angle??

    3. The attempt at a solution

    I am unable to guess the scenario. What does this mean?

    Hi ritwik06! :smile:

    It just means where the line at 30º to straight-across hits the other bank. :wink:

    (so straight-across would be 0º upstream)
