3. A boat travels at 3.5 m/s with respect to the water in a river, while the velocity of the river itself is 1.2 m/s. The boat starts at a point on one shore and travels to a point directly across on the opposite shore. If the river is 62 m wide, how long does it take the boat to cross?

A boat can travel at a speed of 4 m/s in still water. A river that is 170 m wide has a current that flows 0.85 m/s due West. a) If the boat points its bow directly across the river, how fast does the boat travel relative to the shore? m/s b) How long will it take to cross the river? s c) How far downriver will it land (the distance on the bank from the point directly across from...

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...

A river is moving east at vWE = 3.97 m/s. A boat starts from the dock heading θ = 33.9 degrees north of west at vBW = 9.12 m/s, relative to the water. The river is w = 1380 m wide. Part (a) Write an expression for the speed of the boat with respect to Earth (vBE) in terms of variables from the problem statement. B) Write an expression for the time t it takes the boat to cross the...

3) 35 pts. Water in a river flows with a component downstream (x-direction) of 6 m/s and a component across the stream (y -direction) of 4 m/s. A boat is attempting to cross the river. The velocity of the boat relative to the water is 20 m/s at an angle of 70 degrees with respect to the x-axis. Determine the velocity of the boat relative to the shore.

A river flows due south with a speed of 2.30 m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.10 m/s . The river is 850 m wide. Part A In which direction should the motorboat 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 4.10 m/s .) Part B What is the velocity of the...
