maddie swims across a 40 m wide river at a 60 degree angle upstream at a...
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 swimmers swims across a river 37.0m wide at 1.25m/s and swims back at 2.00m/s. what is the swimmers average speed?
A swimmer swims in still water at a rate of 2.6 m/sec. At what angle upstream must the swimmer aim in order to arrive at a point directly across from the starting point if the water current is 1.95 m/sec?
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 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 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?
A person can swim with a speed of 2.05m/s. A 34.2 m wide river flows with a velocity of 4.25m/s[N]. a. if a person swims directly across the river, what will be his velocity? b. If a person swims directly across the river how long will it take him to reach other side? c. If person wants to swim directly across the river. Is this possible? why or why not?
A 260 -m-wide river has a uniform flow speed of 1.5 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 3.6 m/s with respect to the water. There is a clearing on the north bank 66 m upstream from a point directly opposite the clearing on the south bank. (a) At what angle, measured relative...
A river has a steady speed of 0.450 m/s. A student swims upstream a distance of 1.70 km and swims back to the starting point. If the student can swim at a speed of 1.40 m/s in still water, how long does the trip take swimming up and down in the current)? If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)

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...
