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?

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 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

2. Alice and Bob are swimming in a river. They start together at the same point on the bank of a wide stream that flows with a speed v. Both move at the same speed c where c> v) relative to the water. Alice swims downstream a distance L and then upstream the same distance. Bob swims so that his motion relative to the Earth is perpendicular to the banks of the stream. He swims the distance L and then...

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?

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)
