PhysicsNEET 2019Uniform circular motion and relative velocity

Motion in a Plane

The speed of a swimmer in still water is 20 m/s. The speed of river water is 10 m/s and is flowing due east. If he is standing on the south bank and wishes to cross the river along the shortest path, the angle at which he should make his strokes with respect to north is given by:

  1. A. west of north
  2. B.
  3. C. west of north
  4. D. west of north

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
