A20.0 kg sled is being pulled across a horizontal surface at constant velocity. the pulling force has a magnitude of 80.0n and is directed at an angle of 30.0º above the horizontal. determine the coefficient of kinetic friction.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
