i have calculated volume and weight from different size hailstones.(adsbygoogle = window.adsbygoogle || []).push({});

i now have to calculate the wind speed needed to keep a hailstone of each size aloft.

i am stuck on which equation to use...

should i solve using

D = 1/2(C*rho*A*v^2) ?

for rho do i plug in the density of air or of each hailstone?

i can only get as far as plugging in values for

(drag coefficient) C=.5 and A for each respective hailstone.

thanks!
