  1. Consider a small boat crossing a river.  The boat's velocity is 5km/h due north and the water has a current of 2km/h due west.  What is the velocity of the boat relative to the shore and what is the angle at which the boat is actually travelling? 
Expert Solution
Step 1

Velocity of boat = 5 Km/h   (north)Velocity of current = 2km/h  (west)

The resultant velocity between boat and current makes the boat to travel in the direction of resultant velocity.
