A river flows in a direction from south west to north east at a velocity of 7.1m/s. A boat captain wants to cross this river to reach a point on the opposite shore due east of the boat's current position. The boat moves at 13m/s. Which direction should it head towards if the resultant velocity is 19.74m/s? a. It should head in a direction 45.0° south of east. b. It should head in a direction 45.0° east of south. c. It should head in a direction 22.6° south of east. d. It should head in a direction 22.6° east of south.

Step 1
1 m/s (from southwest to northeast) - Boat velocity (\( \vec{v}_b \)) = 13 m/s - Resultant velocity (\( \vec{v}_r + \vec{v}_b \)) = 19.74 m/s Show more…

The captain of a boat wants to travel directly across a river that flows due east with a speed of $1.00 \mathrm{~m} / \mathrm{s} .$ He starts from the south bank of the river and heads toward the north bank. The boat has a speed of $6.10 \mathrm{~m} / \mathrm{s}$ with respect to the water. In what direction (in degrees) should the captain steer the boat? Note that $90^{\circ}$ is east, $180^{\circ}$ is south, $270^{\circ}$ is west, and $360^{\circ}$ is north.

A 140-m-wide river flows due east at a uniform speed of 3.4 m/s. A boat with a speed of 7.2 m/s relative to the water leaves the south bank pointed in a direction 26° west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west. (c) How long does it take for the boat to cross the river?

A river flows due east at $1.50 \mathrm{~m} / \mathrm{s}$. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of $10.0 \mathrm{~m} / \mathrm{s}$ due north relative to the water. (a) What is the velocity of the boat relative to the shoret (b) If the river is $300 \mathrm{~m}$ wide, how far downstream has the boat moved by the time it reaches the north shore?
