How do I make a projectile go in an arc?

Hi, thanks for reading!

I am struggling with how to make a projectile go in an arc; I was following a tutorial on the dev forum but can't quite figure out how to modify the speed on it.

https://devforum.roblox.com/t/modeling-a-projectiles-motion/176677

local t = 0.5;
local mouse = game.Players.LocalPlayer:GetMouse();
local hrp = game.Players.LocalPlayer.CharacterAdded:Wait():WaitForChild("HumanoidRootPart");
local bball = script.Parent:WaitForChild("Handle");

mouse.Button1Down:Connect(function()
    local g = Vector3.new(0, -game.Workspace.Gravity, 0);
    local x0 = hrp.CFrame * Vector3.new(0, 2, -2)

    -- calculate the v0 needed to reach mouse.Hit.p
    local v0 = (mouse.Hit.p - x0 - 0.5*g*t*t)/t; -- The 0.5 tracks distance travelled

    -- have the ball travel that path
    local c = bball:Clone();
    c.Velocity = v0;
    c.CFrame = CFrame.new(x0);
    c.CanCollide = true;
    c.Parent = game.Workspace;
end)

I was wondering if anyone knew how to do it an easier way, and If you can do it w/ BodyForces and how.

Thanks!
