Extracted text: velocity (V), as well as the ball diameter (d) and its angular speed (). It is assumed that the he drag force Fp acting on a baseball is a finstion ofc the air density (p), viscosity (µ) and 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".
