Textbook Problem

The amount of power that can be generated by wind is determined by the equation

$P=\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.D\times S^3$

where P is the power in watts, D is the density, and S is the wind speed in meters per second (m/sec). Because D = 1.293 kg/m³, we can rewrite the equation as

$P=0.65\times S^3$

How much power (in watts) is generated by the following wind speeds: 2 meters per second, 6 meters per second, 10 meters per second, 12 meters per second?
