How Do i Make this FireBall aim at the mouse?

https://gyazo.com/ad7b0ec9c1cc69ce7b40119e41d8f684

here is the script that fires a Remote Event when Q is pressed

wait(2)
local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local CoolD = 0
mouse.KeyDown:Connect(function(key)
	local Key = key:lower()
	if key == "q" and CoolD == 0 then
		CoolD = 1
		print("Fired")
		script.FireBallShoot:FireServer()
		wait(1)
		CoolD = 0
	end 
	
	
end)

The script Above is in a local Script

here is the script that makes the body velocity and shoots where the humanoidRootPart is facing

script.Parent.FireBallShoot.OnServerEvent:Connect(function(Player)
	local ball  = game.ReplicatedStorage.FireBall:Clone()
	ball.CFrame = Player.Character.HumanoidRootPart.CFrame
	
	local BodyV = Instance.new("BodyVelocity")
	BodyV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
	BodyV.Velocity = Player.Character.HumanoidRootPart.CFrame.LookVector * 50
	BodyV.Parent = ball
	ball.Parent = workspace
	
end)

The script above is located in a server script

I would like it to shoot where the mouse is pointing. PS. the ball is located in Replicated Storage

thx in advance
