When a baseball flies through the air, the ratio f[tex]_{quad}[/tex] / f [tex]_{lin}[/tex] of the quadratic to the linear drag force is given by
[tex]\frac{f_{quad}}{f_{lin}}[/tex] = [tex]\frac{cv^{2}}{bv}[/tex] = [tex]\frac{\gamma D}{\beta}[/tex] v = (1.6 x 10[tex]^{3}[/tex] [tex]\frac{s}{m^{2}}[/tex]) Dv.
Given that a baseball has a diamater of 7 cm, find the approximate speed v at which the two drag forces are equally important. For what approximate range of speeds is it sage to treat the drag foce as purely quadratic? Under normal conditions is it a good approximation to ignore the linear term?
f[tex]_{lin}[/tex] = bv
f[tex]^{quad}[/tex] = cv[tex]^{2}[/tex]
Dumb question in starting this, does the b here represent slope? I can't find a definition of the variable in my text...
