Problem 7
A German 280 mm armor piercing projectile weighs 666 lbm and is about 34 in. in length.
It strikes a British warship in the 0.43″ thick vertical side plating at an angle of 10° from
horizontal along the path depicted later. The initial impact velocity is 1900 ft/s. Determine
the residual velocity of the shell after passing through each compartment and how far
through the ship it will go (i.e., in which compartment will it stop)
Assume the density of the armor plate to be ρ = 0.283 lbm/in
