The highest water slide in the world with the corresponding name Verruckt, which in German means “crazy”, opened 10 July of this year in Kansas City (Kansas). Her height is 51 meters, which allowed to add the attraction to the Guinness Book of Records, as the highest water slide in the world /esoreiter.ru/. Slide has smooth waveform, so if you dare to ride it, then after the first 17-story drop at a 60 degree angle you throws up before you overcome the second 18-meter fall and then safely land in plunge pool. The speed of descent from the hill reaches 29 m / s, therefore, the descent itself lasts only 10 seconds. Gene Van Buren (physicist at Brookhaven National Laboratory in New York), shared his impressions: “In the structure of this water slide the relationship between speed, gravity and friction, which in the end gives not only an unforgettable feeling of steepness descent, but also guarantees safety. “Climbing to the top the slides of a person before the descent must be tied to the rubber the raft. This allows not only to avoid any injuries, but also accumulate kinetic energy, which is substantially accelerates the movement of the descending.
The steepness and length of the pipe are crucial in containing a man descending from the gap from the hill. If a person glides along the pipe level, moving parallel to the earth, gravity will be push him down with the same force with which the pipe pushes him back. So, instead of accelerating the movement, the ultimate human will stop smoothly. But if the pipe has a slope, then the acceleration force will not be completely the opposite of gravity. Therefore from the corner the slope of the pipe depends on the acceleration of a person descending from a hill. “The longer and higher the descent, the smoother the lower should be half slide. Otherwise, if the descent is too steep and fast, then a person will fly outside the pipe and break, “Van Buren is sure. Downhill Verruckt people say they experienced feeling of weightlessness. Van Buren explains this by saying that the current the pipe water minimizes friction on its surface, which really during the descent allows you to feel for a few seconds weightlessness. At the moment when the rubber raft for a few seconds separates from the hill, people descending can feel weightlessness. However, a feeling of free fall in some people besides acute sensations can cause panic and fear. Van Buren said that slide developers took this moment into account and equipped the ride a regulating device that, at the request of the client, can be made its descent, both with a concomitant feeling of weightlessness, and without him.
