A boat is crossing a river where water flows at 4 m/s. If the boat is moving with water speed of 6 m/s, aiming straight toward the opposite river bank as seen by a person on the boat: (i) What are the two components of the velocity of the boat as measured by someone at rest on the river bank? (ii) What is the ground speed of the boat?
