I do not think this is actually a homework question. Can you provide more detail on what you want?

The generic formula is KE=½mv2, where m is the projectile mass and v is the velocity. You can take the values at the muzzel or at the target. The KE at the target is less due to air resistance.

A 1000 kg projectile launched at 1000m/s has KE=0.5GJ. For a real world example, look at
