Question

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 ρ = 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.

(C_D(drag coefficient) is 0.5 , and u is constant)

Ball's rpm is 2266 per minute.

Determine the scale of the distance the baseball moves to y-axis direction,by rotation, when the ball meets the batter.
