From Wiktionary under the GNU Free Documentation License. Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. There is debate over whether mathematical objects such as numbers and points exist naturally or are human creations. The mathematician Benjamin Peirce called mathematics "the science that draws necessary conclusions". Albert Einstein, on the other hand, stated that "as far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality." Through the use of abstraction and logical reasoning, mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements. Mathematics continued to develop, for example in China in 300 BCE, in India in 100 CE, and in Arabia in 800 CE, until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that continues to the present day. Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, and the social sciences. Applied mathematics, the branch of mathematics concerned with application of mathematical knowledge to other fields, inspires and makes use of new mathematical discoveries and sometimes leads to the development of entirely new mathematical disciplines, such as statistics and game theory. Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind, although practical applications for what began as pure mathematics are often discovered.

Given the weight, brake horsepower, coefficient of friction between the tires and the road surface, wind resistance , assuming a dry, level road, adding the weight of the driver and perhaps several more factors, what is the mathematical formula to compute the top speeds of automobiles? Also, would automobile manufactuers know the formula and if so, would they give it? Asked by Wolf - Fri Jul 3 01:56:16 2009 - - 1 Answers - 0 Comments A. It depends on how the car is geared. Some cars might hit redline in top gear before making it to their theoretical maximum velocity. But if we assume the car has continuously variable gear ratios, then power (measured at the wheels) and aerodynamic drag are the deciding factors. Essentially, the car will continue to accelerate until the power dissipated by drag is equal to the power output by the engine. The power dissipated by drag is proportional to the velocity cubed, so for a car with negligible rolling resistance at high speeds, to double your top speed, you'd need 2^3 = 8 times as much power. That's why cars with 800 horsepower can't go eight times as fast as cars with 100 horsepower. They can really only go about twice as fast. [cont.] |
