2. A swimmer wants to swim across a river that rus east to west with a current of 0.5 m s1 and is 30 m wide. He plans to swim from the south bank of the river to the north bank and can swim at a steady speed of 2 m s-1, current (a) If he wants to arrive on the north bank directly north of his starting point (the point directly on the opposite side of the river), what...
A swimmer wants to cross a river, from point A to point B, as
shown in the figure. The distance d1 (from A to C) is 200 m, the
distance d2 (from C to B) is 150 m, and the speed vr of the current
in the river is 5 km/hour. Suppose that the swimmer's velocity
relative to the water makes an angle of θ=45degrees with
the line from A to C, as indicated in the figure.To swim directly from...
A swimmer heads directly across a river, swimming at her maximum speed of 1.60 m/s relative to the water. She arrives at a point 40.0 m downstream from the point directly across the river, 67.0 m wide. In what direction (as an angle relative to a direct line across the river) should the swimmer aim instead, so that she arrives at the point directly opposite her starting point?
A swimmer wants to cross a river, from point A to point B, as shown in the figure. The distance d1 (from A to C) is 200 m, the distance d2 (from C to B) is 180 m, and the speed of the current in the river is 1.0 m/s. Suppose that the swimmer's velocity relative to the water makes an angle of 45 degrees with the line from A to C, as indicated in the figure. To swim directly...
Q2
1. Kinematics of swimming A swimmer swims directly across a river of width L that flows with a constant and uniform speed uo. (a) If the swimmer swims with constant speed to. how long does it take them to cross the river? (b) How far downstream of their starting point does the swim- mer reach the opposite shore? (c) What is the minimum speed to that will allow the swimmer to cross the river? 2. Kinematics of swimming The...
A 400.0-mm-wide river flows from west to east at 30.0 m/min. Your boat moves at 90 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 (Figure 1). B)What distance will you have traveled? D)To reach...
Suppose at one point along the Nile River a ferryboat must travel straight across a 1.22-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.31 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 27.1 mph in still water. If the captain points the boat directly at the target location on the east bank of the river, how far downstream will...
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...
You want to swim straight across a river that is 76 m wide. You find that you can do this if you swim at an angle of θ = 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ = 0° while directly across the river is θ = 90°).

A swimmer heading directly across a river 200 m wide reaches the opposite bank in 6 min 40 s, during which time she is swept downstream 480 m. How fast can she swim in still water? What is the speed of the current?
