A distance between pitcher and batter = 18.39m A ball's velocity u=41.52m/s diameter D=0.074m mass m=145.5g Air's density rho = 1.18kg/m^3 viscosity μ = 1.86E-05 Pa*s kinetic viscosity ν= 1.58E-05 m^2/s. In the coordinate system, following thrown baseball, the origin is center of the ball. x-axis is the direction of the thrown ball, z-axis is rotation axis. Required:
Determine the scale of the distance the baseball moves to y-axis direction, by rotation, when the ball meets the batter.
