Ok Gun Math Gurus - this is for you

After my Army days I went back to school to get my teacher's certificate. My specialty was Middle School Physical Science so I took several Physics courses.
During one "Techniques" class the professor showed us a demonstration model he was quite proud of and how it demonstrated "One of Newton's Laws" until a couple of us Physics types pointed out it was a combination of several of his laws, etc.
He just looked at us and said he'd been told "Physics types just make simple things complicated" and we all laughed.
OP example is like that -- should have been another zero in the weight of the bullet, and it should be "mass" not weight among other things.
My vote for "best answer" is by "shootuadeal"
"The answer is 0, the cart is going zero due to the 150lb guy being blown off the end of it in a somersault will have little effect on the cart."🤣

You must have forgotten the time when Earl, after starving for months in the jungle grabbed his Ma-Duece and all 70 Lbs. of him mowed down a brigade of NVA, firing from hip. Changing out white hot barrels with one hand between rounds while firing with the other. The problem assumes a real man, darn it.

Ain't too many men like Earl......

I got 0.8 feet per second.
1400 grain bullet. Must be shooting an advanced potato gun.
750 pound combo of man and cart. Man stays stationery, somehow.
3000 fps bullet (assuming Russet or comparable spud)

An online calculator that calculates the recoil energy, impulse, and velocity of a firearm according to the firearm's weight, powder charge, bullet weight, and bullet muzzle velocity.3 -
Or in short. You cannot move a target with terminal energy when the shooter is on the cart.(if no air resistance they will perfectly cancel out)
if he misses cart will move with the recoil.
If he’s not on the cart you can move it with the terminal energy
but in the problem. Whatever energy is lost from wind resistance will be the only force slightly moving the cart in the direction of recoil
the recoil energy = terminal energy+energy lost to atmospheric
recoil 100%=almost 100+ tiny bit lost to atmospheric drag
since terminal energy isn’t equal in this case with air resistance it is unbalanced, with slightly more recoil than terminal
if the bullet splatter and doesn’t deliver all its energy in a linear force, this will further increase the movement of the cart with recoil
lets nerd it up some more ,
above I’m talking about overall forces. Of course the recoil energy is first so the cart will roll with the recoil first, then stop (assuming no air resistance, target perfectly absorbs energy directly opposite the recoil)
but if there is significant air resistance or bullet splatting wasting energy the cart will maintain some of the velocity imparted from the recoil, cause the terminal energy quite equal
it doesn’t matter weight of the rifle or the man, only the total weight of the cart with everything on it

That calculator chart is a hoot, thank you for sharing.

My worst nightmares contain STORY PROBLEMS!!! Have hated them ever since Elementary school!
I have been told that I have an "Analytical Brain" 😁 I guess that's better than "Abby Normal"
😁
