A good rule of thumb to remember is that a projectile traveling at 3 km/s
has a kinetic energy about equal to its weight in high explosives.
Since the terminal velocity of the V-2 was no where near 3 km/s, the
kinetic energy of its impact would not be nearly as great as the yield of
its HE warhead.
