You are using velocity in your calculations for acceleration.

You should be comparing kinetic energy ke=.5mv^2

Do the math your way.

Tell me if the Boeing still has 10x the inertia at the same speed.

I was pointing out how you are using velocity in place of acceleration in your equation.

Given your data of two projectiles, seeing which one is most destructive, you should compare kinetic energy as you have velocity in meters/sec and mass in kg. To calculate force you need mass in kg and acceleration in meters/sec^2 (m/s^2).
