3.35 Crossing the River I. A river flows due south with a speed of 2.5 m/s. You steer a motorboat across the river; your velocity relative to the water is 4.2 m/s due east. The river is 900 m wide. (a) What is your velocity (magnitude and direction) relative to the earth? (b) How much time is required to cross the river? (c) How far south of your starting point will you reach the opposite bank? 3.36 • Crossing the River II. (a) In which direction should the motorboat in Exercise 3.35 head to reach a point on the oppo- site bank directly east from your 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 time is required to cross the river?
