A boat starting on one side of the river heads to the south with a speed of 1.5 m/s, the river flows to the east at .8 m/s. What is the resultant velocity to the side of the river? And if the river is 50 m wide calculate the displacement of the boat

  1. velocity:
    magnitude=sqrt(.8^2+1.5^2)
    direction: arctan .8/1.5 from the normal to the East

    Displacement=50/(.8/1.5) magnitude, same angle as above.
