A swimmer, capable of swimming at a speed of 1.90m/s in still water (i.e., the swimmer can swim with a speed of 1.90m/s relative to the water), starts to swim directly across a 1.93-km-wide river. However, the current is 1.24m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?

A swimmer, capable of swimming at a speed of 1.02 m/s in still water (i.e., the swimmer can swim with a speed of 1.02 m/s relative to the water), starts to swim directly across a 2.96-km-wide river. However, the current is 0.550 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?
A swimmer, capable of swimming at a speed of 1.60 m/s in still water (i.e., the swimmer can swim with a speed of 1.60 m/s relative to the water), starts to swim directly across a 2.67-km-wide river. However, the current is 1.40 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river? (Write on paper)
A swimmer, capable of swimming at a speed of 1.5 m/s in still water (i.e., the swimmer can swim with a speed of 1.5 m/s relative to the water), starts to swim directly across a 3.0-km-wide river. However, the current is 0.91 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? Incorrect: Your answer is incorrect. s (b) How far downstream will the swimmer be upon reaching the other side...

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 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?
1) . A passenger on a moving train walks at a speed of 1.90 m/s due north relative to the train. The passenger's speed with respect to the ground is 4.5 m/s at an angle of 31.0° west of north. What are the magnitude and direction of the velocity of the train relative to the ground? 2) A ship sets sail from Rotterdam, The Netherlands, heading due north at 8.00 m/s relative to the water. The local ocean current is...
A swimmer is able to swim at a speed of 0.92 m/s in still water. (a) How long does it take the swimmer to go a distance of 1590 m in still water? Call this time t1.(b) The swimmer then decides to swim the same distance in a river having a current with a speed of 0.53 m/s. How long does this take if she swims with the current? Call this time t2. (c) How long does it take her...
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?
An athlete crosses a 21 m wide river by swimming perpendicular to the water current at a speed of 0.35 m/s relative to the water. He reaches the opposite side at a distance 38 m downstream from his starting point. a) How fast is the water in the river flowing with respect to the ground in m/s? b) What is the speed of the swimmer with respect to a friend at rest on the ground in m/s?
