I'm also of opinion that the grr is not quite up to the job...
For a physics problem I would make some simplifying assumptions, like you aim and hit the center of mass.
Then I should be able to calculate the force needed to tip a free-standing target over far enough that the downward (gravity) vector from the c.o.g. points outside of the base... that's in essence what causes an object to fall over or tip over.
So... mass of the target, rough dimensions, and front-back measurement of the base... then it's doable.
The ke remaining of the bullet as it strikes the ram at x distance, will translate into a force F=ma, so the question becomes how much force to tip the ram beyond its base... whatever units the various values come in, I will convert them to a single standard.
I think you're in the ball park. ft-lb/sec is a measure of power, like Kw, I'm thinking more on lines of energy and force.
I'm thinking the target is either 3/8 or 1/2" steel...
Will work on it more after my upcoming meetings in my consulting gig.
this thing has got me intrigued however...!
