I made a ralldoll death but how do I make it fly when the player die?

I would use a VectorForce like this

game.Players.PlayerAdded:Connect(function(p)
    p.CharacterAdded:Connect(function(c)
        c.Humanoid.BreakJointsOnDeath = false

        c.Humanoid.Died:Connect(function()
            for _, v in pairs(c:GetDescendants()) do
                if v:IsA("Motor6D") then
                    local logic0, logic21 = Instance.new("Attachment"), Instance.new("Attachment")
                    logic0.CFrame = v.C0
                    logic21.CFrame = v.C1
                    logic0.Parent = v.Part0
                    logic21.Parent = v.Part1


                    local logic1 = Instance.new("BallSocketConstraint")

                    logic1.Attachment0 = logic0
                    logic1.Attachment1 = logic21
                    logic1.Parent = v.Parent

                    v:Destroy()
                end
            end
            c.HumanoidRootPart.CanCollide = false

			local hrp = c.HumanoidRootPart
			local rootAttachment = hrp.RootAttachment

			local force = Instance.new("VectorForce", hrp)
			
			force.Attachment0 = rootAttachment			
			force.Force = Vector3.new(math.random(-100, 100), 0, 500)
        end)
    end)
end)
