## Historic Riverboat Sails Again with Revamped Plumbing System

The wolf, goat and cabbage problem is a river crossing puzzle. It dates back to at least the 9th century, [1] and has entered the folklore of a number of ethnic groups. Once upon a time a farmer went to a market and purchased a wolf , a goat , and a cabbage. On his way home, the farmer came to the bank of a river and rented a boat. But crossing the river by boat, the farmer could carry only himself and a single one of his purchases: the wolf, the goat, or the cabbage.

The farmer's challenge was to carry himself and his purchases to the far bank of the river, leaving each purchase intact. How did he do it? The first step that must be taken is to let the goat go across the river, as any other actions will result in the goat or the cabbage being eaten.

When the farmer returns to the original side, he has the choice of taking either the wolf or the cabbage across next. If he takes the wolf across, he would have to return to get the cabbage, resulting in the wolf eating the goat.

If he takes the cabbage across second, he will need to return to get the wolf, resulting in the cabbage being eaten by the goat. The dilemma is solved by taking the wolf or the cabbage over and bringing the goat back. Now he can take the cabbage or the wolf over, and finally return to fetch the goat. Note: the key to the solution is realizing that one can bring things back emphasized above.

This is often unclear from the wording of the story, but never forbidden. Knowing this will make the problem easy to solve even by small children. The focus of the puzzle is not just task scheduling, but creative thinking, similarly to the Nine dots puzzle. The puzzle is one of a number of river crossing puzzles , where the object is to move a set of items across a river subject to various restrictions. In the earliest known occurrence of this problem, in the medieval manuscript Propositiones ad Acuendos Juvenes , the three objects are a wolf, a goat, and a cabbage, but other cosmetic variations of the puzzle also exist, such as: wolf, sheep, and cabbage; [4] [2] , p.

According to the legend, when a tiger has three cubs, one of them will be a leopard rather than a tiger, and more fierce than the others. Following this legend, the subject of a tiger with her cubs became a traditional subject for art in east Asia.

This depicts a puzzle equivalent to the puzzle of the wolf, goat, and cabbage, asking how the mother can do this without leaving the leopard cub alone with any of the other tiger cubs. The puzzle was a favorite of Lewis Carroll , [13] and has been reprinted in various collections of recreational mathematics. Gurdjieff cites this riddle as "The Wolf, the goat and the cabbage".

He notes, "This popular riddle clearly shows that In the Class of episode "Westley Side Story", Sunny and his students perform a similar exercise involving a chicken, a coyote and a sack of corn.

The Between the Lions episode "Farmer Ken's Puzzle" portrays it being made into a computer game with a cat, a hen, and a sack of seeds. In the Bull episode "Justice for Cable", Benny begins a riddle with "a man has a fox, a duck, and a bag of beans". Bull inexplicably declares "There is no answer", and everyone believes him. In some parts of Africa, variations on the puzzle have been found in which the boat can carry two objects instead of only one.

When the puzzle is weakened in this way it is possible to introduce the extra constraint that no two items, including A and C , can be left together. From Wikipedia, the free encyclopedia.

## Relative Motion- Rain Man / River Boat Problems

On occasion objects move within a medium that is moving with respect to an observer. For example, an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example, a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this, the magnitude of the velocity of the moving object whether it be a plane or a motorboat with respect to the observer on land will not be the same as the speedometer reading of the vehicle. Motion is relative to the observer. The observer on land, often named or misnamed the "stationary observer" would measure the speed to be different than that of the person on the boat. The observed speed of the boat must always be described relative to who the observer is.

In this case, the vectors are orthogonal and you just use the pyth. A motor boat heads east across a river at 5. The vertical acceleration.

To solve river boat problems, we need to understand two concepts: The speed of a boat relative to the water is equal to the speed of boat in still water. What is the time taken by the boat to travel a distance of 30 km downstream? In upstream motion, the speed of the boat is equal to the difference of the speed of boat in still water and the speed of river water. Problem: A motorboat going downstream overcame a raft at a point A; one hour later it turned back and after some time passed the raft at a distance 6. Find the flow velocity. The velocity of the river water is?

Поверь мне, постараюсь изо всех сил. ГЛАВА 52 Клуб Колдун располагался на окраине города, в конце автобусного маршрута 27. Похожий скорее на крепость, чем на танцевальное заведение, он со всех сторон был окружен высокими оштукатуренными стенами с вделанными в них битыми пивными бутылками - своего рода примитивной системой безопасности, не дающей возможности проникнуть в клуб незаконно, не оставив на стене изрядной части собственного тела. Еще в автобусе Беккер смирился с мыслью, что его миссия провалилась. Пора звонить Стратмору и выкладывать плохую новость: поиски зашли в тупик. Он сделал все, что мог, теперь пора ехать домой. Но сейчас, глядя на толпу завсегдатаев, пытающихся попасть в клуб, Беккер не был уверен, что сможет отказаться от дальнейших поисков.
