Physics 12 - Quiz #2

Crossing the Fraser

Solution:

 
a) The vector equation for the velocity of the boat with respect to the shore is given by,
 

Vbs = Vbw + Vws

  where Vbw = 3.5 m/s in the assigned direction of East

            Vws = 2.5 m/s in the assigned direction of South

b) We can now draw the vector diagram the represents the vector equation.

 
 
c) We can now use our knowledge of trigonometry to solve for the velocity of the boat w.r.t. the shore, Vbs.
