Adog wishes to swim across a slow-moving stream. the dog can swim at 2.0m/s in calm water. the velocity of the current is 3.0m/s. the distance directly across the stream is 50m.
a) how long does it take dog described above to swim 50m in a bost of water that has no current?
b) how far downstream will current have carried the dog in the time it takes the dog to get across the stream?
c) calculate dog’s resultant velocity relative to bank from where the dog started.
