A well$-$hit golf ball $($diameter D $=1\mathrm{.}69$ in$,$ weight W $=0\mathrm{.}0992$ lb$)$ can travel at u $=200$ f$($t$)/($s$)$ as it leaves the

tee. The figure below shows the effect of surface roughness on the drag coefficient of a sphere.

a$1\mathrm{.}57\backslash$times $10^(-6)$f$($t$^(2))/($s$)$ and a density of $2\mathrm{.}38\backslash$times $10^(-3)$slugsfl$^(1).$ Express your answers

in units of lb$\_($s$).$

bD is the drag force and v is the kinematic viscosity.
