A boy is attempting to swim directly across a river; he is able to swim at a speed of 0.439 m/s relative to the water. The river is 2.27 m wide and the boy ends up at 4.78 m downstream from his starting point. (a) How fast is the current flowing in the river? m/s (b) What is the speed of the boy relative to a friend standing on the riverbank? m/s

An athlete crosses a 29 m wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance 35m downstream from his starting point. How fast is the water in the river flowing with respect to the ground in m/s?
The figure shows a swimmer who wants to cross a river, from point A to point B, as shown in the figure. The distance d1 (from A to C) is 200 m, the distance d2 (from C to B) is 150 m, and the speed of vr of the current in the river is 5 km/hr. Suppose that the swimmer's velocity relative to the watermakes an angle of θ= 45 degrees with the line from A to C, as indicated in the figure. Q: To swim directly from A to B, what speed us, relative to the water, should the swimmer have? Express the swimmer's speed numerically in km/hr.
A ferryboat has a still water speed of 10.3 km/hr. Its helmsman steers the boat due north across a river that runs with a current of 5.2 km/hr east. If the trip lasts 1.5 hr, how wide is the river? How far east does the ferry travel during the trip?
Three cars, A,B, and C, are moving along a straight section of highway. If the velocity of A relative to B is +60m/s and the velocity of A relative to C is +20m/s, then what is the velocity of C relative to B?
A boat can travel 2.3 m/s in still water. If the boat travels across a stream whose current is 1.2 m/s what is the boat's velocity ( magnitude and direction) compared to the shore? What will the position of the boat be after 3.00 s?
A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 12 m/s. A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 16 m/s relative to the air, in what direction should they head in order to move directly south?
A cameraman on a pickup truck is traveling westward at 20 km/h while he videotapes a cheetah that is moving westward 39 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then run at 46 km/h eastward, as measured by a suddenly nervous crew member who stands alongside the cheetah's path. The change in the animal's velocity takes 1.9 s. What are the (a) magnitude and (b) direction of the animal’s acceleration according to the cameraman and the (c) magnitude and (d) direction according to the nervous crew member?
Brenda is flying a small airplane. Her velocity, with respect to the air around her is 45.0 m/s south. The air is also moving with a velocity of 9.9 m/s east. To an observer on the ground, what is the magnitude of Brenda’s velocity? 35.1 m/s 46.1 m/s 27.5 m/s 54.9 m/s
