Questions and Answers

What is the formula for the kinetic energy produced by the wind when mass ma is moving at a velocity V?

E = ma V2
E = ½ ma V2 (correct)
E = ½ ma V
E = 2ma V

Which parameter represents the kinetic energy of air per unit volume of air?

Ev = ½ da V2 (correct)
Ev = ½ da V
Ev = da V2
Ev = 2da V2
