A swimmer attempts to reach the other side of the Fraser River, which has a width of 35m near
Hell's Gate1. This swimmer can swim at 11.6m/s, but Fraser River has a downstream current moving
at roughly 0.50m/s to the west.
a) If the swimmer heads straight north for the other side of Fraser River, how long will that take?
b) If there were NO current, would the swimmer take just as long as in question "a"? Why or why not?
c) Draw and find the swimmer's resultant velocity for question "a" while taking the current into
consideration.
*d) In which direction should the swimmer head to reach the other side of Fraser River while moving
in a straight line?

    HDT Truck Company HDT Truck Company has been located in Crown Point, Indiana, since 1910. Its only products— large trucks—are built to individual customer specifications. The firm once produced automobiles but dropped out of the auto business in 1924. The firm nearly went out of business in the late 1930s, but by 1940 its fortunes were buoyed by receipt of several military contracts for tank retrievers—large-wheeled vehicles that can pull a disabled tank onto a low trailer and haul it...
