I watched Juressic World.And there they are trying to destroy Trex to shooting it.I measn people using guns to kill or defuse a Trex.
I have a duck.And when duck turns upside down,I mean when its back touches ground it can't get up itself.So here my idea
We can turn Trex Upside down,again I mean the back touches ground,Trex cannot get up cause he has two legs.
Is my idea true ?

Note:Maybe this is not a biology question.I don't know

It would require a substantial amount of work to get a T-rex to fall directly onto its back. Animals, of all sizes, typically rotate their limbs and body when falling so that they don't fall on their backs, but onto their feet or sides instead. Getting a T-rex to fall onto its back is probably much harder than making a cat fall directly on its back, and I've never even been able to do the latter.
 
Ryan has it nailed exactly.

There were very powerful elephant guns in use in the first half of the 20th Century. For example - the 600 nitro express, which was a side by side rifle that was very heavy. These rifles were actually overpowered as they were designed to stop a charging very large mammal -elephant or rhino. They did exactly that. And probably damaged the soft tissue of the shooter's shoulder.

If we were actually having to deal with large charging dinosaurs with same same mass as an elephant then we already have the technology to instantly flatten said beastie, dating from about 1903. Old but effective. Which would derail the plot -- I am guessing.
 
I recall seeing a dinosaur show on History Channel a few years back and they maintained that, due to their great mass, if a T-Rex fell over for any reason, it would be guaranteed to break bones and be crippled. Therefore, it wouldn't be necessary to make it fall on its back. Making it fall any way at all, would put it out of commission.

It that's true, it would mean the T-Rex wasn't the fast-running predator of the movies, but a scavenger that actually strolled around at a safe, slow pace, sniffing around for things that were already dead by other means. It couldn't risk a chase or a battle with prey.

Interesting.

From here
https://en.m.wikipedia.org/wiki/.600_Overkill
the muzzle velocity is up to 2450 Fps and the muzzle energy is up to 11995 Ft. Lbs. Or 16172 Joules

comparing to other other firearms from

The https://www.physicsforums.com/wiki/7.62%C3%9751mm_NATO was a Nato round M14,( Vietnam) - apparently not enough to stop a T-rex. ( M16 similar )
The https://www.physicsforums.com/wiki/7.62%C3%9739mm was soviet ie the famous AK47
The https://www.physicsforums.com/wiki/.50_BMG Browning machine gun, sniper ammo - better choice.

Seems like the regular ammo issue for gun enthusiasts and regular army infantry would be lacking in penetration power - maybe only 10 inches through tough skin and flesh.
T-Rex might be annoyed. Lucky shot to vital organs - possible but unlikely.

Several darts which inject a sedative?
I think that has been used in real life with less dangerous animals.
Harden the darts with depleted uranium if necessary.
