Question on making a certain effect

So i have a raggdoll, and an object (milk crate for example) is there a way i could make so the object flies towards a ragdoll, (that is standing) and when the object hits the ragdoll, he falls over, i cant find any tutorials for this, and i dont know how to do it, and i cant use an npc, i need to use a ragdoll. anyone have any ideas?

You can weld the ragdoll and set the strength of the weld low enough so the weld breaks when the prop collides with the ragdoll. But still strong enough so the ragdoll doesn’t just fall over.

Or you could download the Sleep N Wake STool and fire it on the ragdoll, then toss an object at the ragdoll and it’ll fall over
