# What is the muzzle velocity of the tank's gun (m/s) ?

A uranium projectile fired from a tank in Iraq has a volume of 338.90 cm3 and an intital kinetic energy of

2.09 × 103 kJ. What is the muzzle velocity of the tank's gun (m/s) ?

The density of uranium is 18.95 g/cm3

M=volume*density=6.422kg

Ek=0.5*M*V^2=2.09x10^3 kJ

V^2= (2*Ek)/(M)

V=25,5 m/s

Note: this initial velocity is not realistic......usually tank gun rounds have an initial velocity of about 900-1000 m/s, Machine-guns have a muzzle velocity around 300-400 m/s ,

25 m/s seem to be a muzzle velocity of a soft-air pistol or of a crossbow....
