A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?

A river flows due east at 2.69 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 12.2 m/s due north relative to the water. What is (a) the magnitude (m/s) and (b) the direction (degrees east of north) of the boat’s velocity relative to shore? (c) If the river is 324 m wide, how far (m) downstream has the boat moved by the time it reaches the north shore?

URGENT A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 110 m/min relative to the water no matter which direction you point it. To cross this river, you start from a dock at point A on the south bank. There is a boat landing directly opposite at point B on the north bank, and also one at point C, 75.0 m downstream from B a)Where on the north shore will you land if you...
