Cats Amazing Ability to Survive Falls Essay -- physics cat cats fall
Your chance of surviving a fall of 50 feet (approximately 4 stories) is well-nigh 50%, while almost no one who fall 6 stories will be around to tell their tale. However, in a contain conducted by Manhattan veterinarians, Drs. Wayne Whitney and Cheryl Mehlhaff, it was discovered that out of 115 cases of cats falling (accidentally) from multi-story heights, 90% of them survived. An flush more than surprising result is that if a cat falls from more than 7 stories its chance of survival doubles, compargond to a cat having fallen from 2 to 7 stories (a story averages about 12 feet). No wonder cats are fabled to fork up nine lives. It turns out that the two most central variables which contribute to the cats survival are its ability to land on its feet and its reaching terminal velocity (both of which involve a fair deal of physics).Whitney & Melhaffs disciplineCats apparent fearlessness concerning heights leads to many accidental falls. In accompaniment so many cats are brought t o veterinarians for treatment after a fall, that in 1976 Dr. Gordon Robinson coined the term feline high-rise syndrome to describe the resulting pattern of injuries. Eleven eld later Drs. Wayne Whitney and Cheryl Mehlhaff at the Animal Medical Center in Manhattan conducted a study over a five month period on cats brought in for treatment after a fall. They compiled a database of 115 cats who strike down a range of two to thirty-two stories, primarily ending their falls on concrete pavement. The mean fall was 5.5 stories. Three of the cats were dead upon comer and 8 more died in the next twenty-four hours, leaving 104 funding cats or about 90%. This is a remarkable statistic.When the height the cats send away is taken into account, it is found that only 5% of the cats who fell seven ... ... a small amount of mass, but also their ability comes from their flying squirrel (relaxed) bewilder upon reaching terminal velocity and from their superb inner gyroscope.Works Cited * Diam ond, Jared.
