How to get the time it will take for a falling part to land using raycast

Basically I want to re create adventure times knife rain and I was wondering how I would go about calculating the time it would take a knife to collide with a surface. This is my code at the moment

local start = ReturnRandomMapXYPosition() + Vector3.new(0,100,0)
			local clone = knife:Clone()
			
			clone.PrimaryPart.Position = start
			clone.Parent = workspace.Game.CleanUp
			
			
			local ray = Ray.new(start, Vector3.new(0, -250, 0))
			local hit2, position = workspace:FindPartOnRayWithIgnoreList(ray, {workspace.GameZone})
			local distance = (start - position).Magnitude
			
			--task.wait() ????
			
			if hit2 then
				Debris:AddItem(clone)
				
				local clone = knife:Clone()
			
				clone.PrimaryPart.Position = position
				clone.Parent = workspace.Game.CleanUp
				
				clone["Knife (Model)"].WeldConstraint.Part1 = hit2
			end

The knives rely on a child LinearVelocity which adds some additional downward force.

Here are the properties for the LinearVeloctyHow can I account for this instance when I calculate the time before I should create the clone and destroy the original knife.
