2. The drag force FD acting on a baseball is a function of the air density (p), viscosity (µ) and velocity (V), as well as the ball diameter (d) and its angular speed (o). It is assumed that the ball spins about an axis which is fixed with respect to the ground. Determine the similarity (Pi) groups and their functional dependence. Select p, V and d as "repeating variables".
