Homework Help: Relative Velocity of swimming

  1. Feb 17, 2010 #1
    1. The problem statement, all variables and given/known data
    A swimmer can swim at a speed of 1.80m/s in still water. If the current in a river 200m wide is 1.0m/s [E], and the swimmer starts on the south bank and swims so that she is always headed directly across the river, determine:

    a) The swimmer's resultant velocity, relative to the river bank.
    b) How long she will take to reach the far shore.
    c) How far downstream she will land (from the point opposite her starting point)

    2. Relevant equations

    3. The attempt at a solution

    a) Draw a vector 1.8m/s north, and then 1.0m/s east?

    If so,


    b) t = d/v

    c) d=v*t
