Homework Answers
(a)
Time taken by the boat to reach to a point directly across,
Time = width of river / speed of boat
t = d / v
(b)
For fastest possible crossing time,
speed of boat, v' = sqrt (v2 + V2)
t = d / v'
t = d / sqrt (v2 + V2)

A boat launches from one shore of a river heading upstream at an angle of 60o to the shore. The boat's speed, relative to the water, is 9 mph and the current of the river flows against the course of the boat in such a way that the boat ends up traveling directly across the river (L to the shore). How fast must the current of the river be flowing if...

A boat can travel at a speed of 4 m/s in still water. A river that is 170 m wide has a current that flows 0.85 m/s due West. a) If the boat points its bow directly across the river, how fast does the boat travel relative to the shore? m/s b) How long will it take to cross the river? s c) How far downriver will it land (the distance on the bank from the point directly across from...

A river is to be crossed by a girl using a row boat.
Assume that the water has uniform velocity, represented above by
the vector labeled H. The rowing speed of the girl and a set of
possible orientation of her boat are also shown. Select the
direction (i.e., F, or D, or ...) in order to cross the river in
the shortest time. (Notice that the number of tries is
reduced.)
For which rowing orientation will the girl land...

3. A boat travels at 3.5 m/s with respect to the water in a river, while the velocity of the river itself is 1.2 m/s. The boat starts at a point on one shore and travels to a point directly across on the opposite shore. If the river is 62 m wide, how long does it take the boat to cross?

URGENT A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 110 m/min relative to the water no matter which direction you point it. To cross this river, you start from a dock at point A on the south bank. There is a boat landing directly opposite at point B on the north bank, and also one at point C, 75.0 m downstream from B a)Where on the north shore will you land if you...

A boat crossing a wide river moves with a speed of 18.0 km/h relative to the water. The water in the river has a steady speed of 8.00 km/h due east relative to the earth. a) If the boat heads due south, determine the speed of the boat relative to an observer standing on the shore. km/h 9. b) What is the angle made between the velocity of the boat relative to the observer and the south direction? 10. c)...

Problem 3.41: Crossing the River, II. A river flows due south with a speed of 1.50m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.40m/s . The river is 800m wide. Part A In which direction should the motorboat head in order to reach a point on the opposite bank directly east from the starting point? (The boat's speed relative to the water remains 4.40m/s .) Part B What is the velocity...
