A women tries to swim perpendicular across the river to the opposite bank at 2.0m/s with respect to the water. If the river is 300m wide and the current in the river is 1.0m/s, determine
a) the women velocity relative to the shore,
b) the distance swept downstream and
c) the time required to swim across the river

You attempt to swim across a river 120 meters wide, and can swim at 2.6 m/s in still water. You set off aiming to arrive a point 50 meters downstream of your starting point. However, you fail to take into account the flow of the water, and because of this you land on the opposite bank 100 meters downstream of your starting point. What is the speed of the flow of water, in m/s?

An athlete crosses a 24.2 m wide river by swimming perpendicular to the water current at a speed of 0.4 m/s relative to the water. He reaches the opposite side at a distance of 45.3 m downstream from his starting point. How fast is the water in the river flowing with respect to the ground?

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?

2. A swimmer wants to swim across a river that runs east to west with a current of 0.5 m s-1 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 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), at...

A river flows due east at 1. 50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water. (a) What is the velocity of the boat relative to the shore? (b) If the river is 300 m wide, how far downstream has the boat moved by the time it reaches the north shore?

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 river flows due east at 2.69 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 12.2 m/s due north relative to the water. What is (a) the magnitude (m/s) and (b) the direction (degrees east of north) of the boat’s velocity relative to shore? (c) If the river is 324 m wide, how far (m) downstream has the boat moved by the time it reaches the north shore?
