You want to swim straight across a river that is 76 m wide. You find that you can do this if you swim at an angle of  = 28 from the upstream direction at a constant rate of 1.5 m/s relative to the water.
 
  At what rate does the river flow? The angle  is measured from the river bank (directly upstream is  = 0 while directly across the river is  = 90). A) 1.3 m/s
  B) 0.70 m/s
  C) 1.6 m/s
  D) 1.8 m/s

Question 2

A small boat is moving at a velocity of 3.35 m/s when it is accelerated by a river current perpendicular to the initial direction of motion. If the acceleration of the current is 0.750 m/s2, what will be the new velocity of the boat after 33.5 s?
 
  A) 25.3 m/s at 82.4 from initial direction of motion
  B) 25.3 m/s at 7.59 from initial direction of motion
  C) 640.1 m/s at 82.4 from initial direction of motion
  D) 640.1 m/s at 7.59 from initial direction of motion
