Cass Ave. Argonne, Illinois 60439-4845 USA, This article provides calculations and examples of the terminal velocity of a hailstone. Web search 03/14/2011, original source: http://www.newton.dep.anl.gov/askasci/phy05/phy05051.htm
  Quoting:
  HAILSTONE: A spherical hailstone weighing 10 gm has a volume of 10 cm^3 since the density is 1 gm/cm^3. REALITY CHECK: The volume = 10 cm^3 = 4/3 *pi* r^3. So r^3 = 2.4 cm^3 or a radius of r = 1.3 cm or a diameter of 2.6 cm (a fairly nominal hailstone -- about an inch in diameter).
  The potential energy of a hailstone weighing 10 gm = 10^-2 kg
  falling from 10 km is: P.E. = m*g*h =
  10^-2 * 9.8 * 10,000 (about 10^-2+1+1 = 10^0 = 1 Joule). Its velocity
  assuming complete conversion of the P.E. to K.E. = 1/2*m*(v)^2
  gives: 1 = 1/2x10^-2*(v)^2 or v^2 = 200 m^2 or about 15 m / sec
