How to make a projectile's motion concave upwards?

Its hard to explain as im rusty in algebra, but i got this script where it has a projectile move in a curved slope (from your humanoidrootpart to your mouses position) and it has a negative acceleration (where it concaves down).

local p = game.Players.LocalPlayer
local m = p:GetMouse()
repeat wait() until p.Character
local c = p.Character
local enabled = true
local t = 1;
local hrp = c:WaitForChild("HumanoidRootPart");
local bball = workspace.Hm;

m.Button1Down:Connect(function()
    local g = Vector3.new(0, -game.Workspace.Gravity, 0);
    local x0 = hrp.CFrame * Vector3.new(0, 2, -2)
    local mp = m.Hit.p--+Vector3.new(0,15,0)
    -- calculate the v0 needed to reach mouse.Hit.p
    local v0 = (mp - x0 - 0.5*g*t*t)/1;

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

What i am trying to do though, is make the slope has a postive acceleration, so that the slope's curve concaves upwards instead, starting as a decreasing slope and ending as an increasing slope when it reaches the destination.. Kinda like this: https://gyazo.com/48e64596375a2505968596c03583230c?token=417006b3cc7e1465d476fc20ae150d70

I have tried doing things, like setting the Gravity value to positive, and messing with the numbers and making them negatives/positives, higher/lower, etc. The closest i have gotten was setting the gravity to positive and making the destination 15 units higher, but the part just concaves downwards and does not appear again.

Anything will help!

Thanks!

Use variable names that are relevant and make sense. User#21908 42 — 6y

local v0 = (mp - x0 + 0.5*g*t*t)/1; brok4d 77 — 6y

@Phlegethon5778 I got most of them variables from a given script on this website, so argue with the dude that uploaded the original not me please. Also, its not even the variables that are the problem Nikkulaos 229 — 6y

@brok4d I tried that and got this result: https://gyazo.com/2608d5754a68adcae874c797e8989f10 Nikkulaos 229 — 6y
