12 A riverboat is shown starting at position A on the east bank of a river. The boat heads towards position B with a speed of 3.8 m/s. But because of a current with a speed of 1.8 m/s, the boat lands on the west bank of the river at position C, a location downstream from B.
Questions: (Each correct answer is worth 2 points)
What is the magnitude of the resultant velocity of the boat?
What is the direction of the resultant velocity of the boat?
