(SOLVED BY SELF!) How to limit how far a projectile can travel and make it go that far?

(SOLVED BY SELF!) Hello! I am trying to make a throwing system and I want my throwing system to allow the projectile to go for example 50 studs maximum. I slightly modified EgoMoose's Modeling projectile motion script which can be found Here. As it stands, my current code is :

local t = 1;
local mouse = game.Players.LocalPlayer:GetMouse();
local hrp = game.Players.LocalPlayer.CharacterAdded:Wait():WaitForChild("HumanoidRootPart");
local bball = script.Parent

mouse.Button1Down:Connect(function()
	if script.Parent.Parent.Parent ~= workspace then
		local g = Vector3.new(0, -game.Workspace.Gravity, 0);
		local x0 = hrp.CFrame * Vector3.new(0, 2, -2)
		
		local pos = mouse.Hit.p
		if (hrp.Position - pos).magnitude > 50 then --this is to make sure it does not travel more than 50 studs
		--im guessing the code to make it go 50 would go here.
		else
			local v0 = (pos - x0 - 0.5*g*t*t)/t;
			local c = bball:Clone();
			c.Velocity = v0;
			c.CFrame = CFrame.new(x0);
			c.CanCollide = true;
			c.Parent = game.Workspace;
		end
	end
end)

This limits the distance, however I don't know how to make it just go that distance. Any help is appreciated. Thanks, BrainDead_Dev.

Edit : I tried something else today and still not working. What I tried :

local t = 1;
local mouse = game.Players.LocalPlayer:GetMouse();
local hrp = game.Players.LocalPlayer.CharacterAdded:Wait():WaitForChild("HumanoidRootPart");
local bball = script.Parent

mouse.Button1Down:Connect(function()
	if script.Parent.Parent.Parent:FindFirstChild("Humanoid") then
		local g = Vector3.new(0, -game.Workspace.Gravity, 0);
		local x0 = hrp.CFrame * Vector3.new(0, 2, -2)
		
		local pos = mouse.Hit.p
		if (hrp.Position - pos).magnitude > 50 then
			local offset = Vector3.new(0,0,50)
			pos = hrp.CFrame * offset
		end
		local v0 = (pos - x0 - 0.5*g*t*t)/t;
		local c = bball;
		script.Parent.Parent.qPerfectionWeld.Disabled = true
		c.qCFrameWeldThingy:Destroy()
		c.CanCollide = true;
		c.Parent = game.Workspace;
		c.Velocity = v0;
		c.CFrame = CFrame.new(x0);
		c.Anchored = true
		
	end
end)

SOLUTION : First I made a part constantly be in front of me, and then I set pos to that parts position. Simple as that
