Swimming at 1.00 m/s relative to still water, a swimmer heads directly across a river of width 95 m. He arrives 35.0 m downstream from the point directly across the river from his starting point.
(a) What is the speed of the current in the river?m/s

(b) At what angle relative to the line perpendicular to the shore should he head to arrive at a point directly opposite his starting point? °

A swimmer, capable of swimming at a speed of 1.80 m/s in still water (i.e., the swimmer can swim with a speed of 1.80 m/s relative to the water), starts to swim directly across a 1.70-km-wide river. However, the current is 1.18 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?

An athlete crosses a 23 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 45 m downstream from his starting point.

Thomas and Ashley are swimming in a river which is 15 m wide. Both swim with a speed u = 1.2 m/s relative to the water, which is flowing downstream at a speed v = 0.25 m/s. They both leave a point on one bank at the same time. Thomas swims directly upstream a distance 15 m, then turns back and swims downstream to his starting point. Ashley points herself so that, taking account of the current, she can swim...

A boat crossing a 254.0 m wide river is directed so that it will cross the river and land on the opposite shore directly across from the starting point. The boat has a speed of 6.20 m/s in still water and the river flows uniformly at 3.10 m/s. Calculate the time required for the boat to reach the opposite shore.

An athlete needs to get across a river. He must reach from point A on one bank to point B, which is directly across from point A on the opposite bank. If he wishes to minimize the total time T it would take to do so, at what angle upstreams (measured from the line AB) should he swim? Let his swimming/rowing speed relative to the water be 6.0 mi/h, and his running speed along the bank be 10 mi/h. The...

A river flows due south with a speed of 1.7 m/s . A man steers a motorboat across the river; his velocity relative to the water is 3.8 m/s due east. The river is 840 m wide. What is the magnitude of his velocity relative to the earth? What is the direction of his velocity relative to the earth? How much time is required to cross the river? How far south of his starting point will he reach the opposite...

Bill and Jill both average swimming speeds of 3.0 m/s, in a pool (that has no current). Bill and Jill go down to the river for a swim, the river has a current of 1.0 m/s straight EAST and is 1.50 x 102 m in width. They are standing on the SOUTH shore. a.Bill, not thinking about the current, jumps in and swims straight across to the North shore. Of course the current affects his resultant velocity and he doesn’t...
