How can I make a destroyable prop? (Like RoCitizens)

I’d like to achieve a part, that when is touched, unanchors and the velocity of what ever touched it is sent through to the part sending it flying.

Not sure what you mean by
“the velocity of what ever touched it is sent through to the part sending it flying.”
but heres the rest

local Debounce = false
script.Parent.Touched:Connect(function()
if not Debounce then
script.Parent.Anchored = false
Debounce = true
wait(1)
Debounce = false
end

He means with one of the constraint movers.
