A dog wishes to swim across a slow-moving stream. The dog can swim at 2.0 m/s in calm water. The current velocity is 3.0 m/s and the distance directly across the stream is 50 m.
A) If the dog points herself directly across the stream, how long will it take to get to the other side?
B) How far downstream will the current have carried the dog when the dog gets to the other side?
C) What was the dog's velocity relative to the bank from where the dog started?
