great mod but one question

[Kugutsu]

Theres two factors which have an effect: the pressure and the momentum.

Pressure can be worked out by: Pressure (N/m2) = Force (N) / Area (m2)

Momentum (or kinetic energy) depends on the speed and the weight of the object, the speed being more important: Kinetic Energy (J) = 1/2 mass (kg) x speed2 (m/s2)

Linking the two is a bit tricky, as you need to divide the kinetic energy by the distance over which the force has been applied to work out the force, however given the mass, speed, area of point and distance from when it hits to when it stops (thats the tricky bit) it should be possible to work out which projectiles are best...
