QUESTION $16$

Fred throws a curveball, so that the speed of the air above the ball is $\backslash (26\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ and the speed of the air below the ball is $\backslash (32\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The diameter of a baseball is $75$ mm and the density of air is $\backslash (1\mathrm{.}2\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ).$ Assuming that the effects of gravity and other forces are negligible, calculate the pressure difference $($in Pa$)$ between the top and bottom of the ball as it moves through the air.

QUESTION $17$

How does this pressure difference result in the curved path of the ball?
