How do I push a player to the ground or make them fall?

I am tyring to make a system where whenever a player gets hit by a chair projectile they fall to the ground and begin ragdolling. I’ve been experimenting with VectorForce and it doesn’t seem to work. This is all I got, any ideas?

Also, I don’t want to use PlatformStand since it makes the player’s body parts collide with the ground.
Tool server script

		local force = Instance.new("VectorForce") 
		force.Force = Vector3.new(-750, -5, -750)
		force.ApplyAtCenterOfMass = true
		force.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
		force.Attachment0 = hitchar.Parent.HumanoidRootPart.RootAttachment
		force.Parent = hitchar.Parent.HumanoidRootPart 

You can use a SurfaceForce, with a custom surface. Here is an example:
local force = Instance.new(“SurfaceForce”)
force.Force = Vector3.new(-750, -5, -750)
force.ForceOrientation = Enum.SurfaceForceOrientation.Attached
force.Attachment0 = hitchar.Parent.HumanoidRootPart.RootAttachment
force.Parent = hitchar.Parent.HumanoidRootPart

I checked the developer documentation, and that isnt a real instance?

why is bro spreading misinformation :sob:
also use linear velocity with a high maxforce, thats what most ppl do
