Chapter 3, Problem 36E(choose chapter or problem)
Problem 36E
Crossing the River II. (a) In which direction should the motorboat in head in order to reach a point on the opposite bank directly east from the starting point? (The boat’s speed relative to the water remains 4.2 m/s.) (b) What is the velocity of the boat relative to the earth? (c) How much lime is required to cross the river?
Exercise:
Crossing the River I. A river flows due south with a speed of 2.0 m/s. A man steers a motorboat across the river; his velocity relative to the water is 4.2 m/s due east. The river is 800 m wide. (a) What is his velocity (magnitude and direction) relative to the earth? (b) How much time is required to cross the river? (c) How far south of his starting point will he reach the opposite bank?

ANSWER:
Solution 36E
is the velocity of the boat relative to the earth towards east
is the velocity of the water relative to the earth towards south
is the velocity of the boat relative to the water
