Teleporting a player instead of Changing it's velocity?

Instead of just making the player go really fast, I want to actually teleport a player based on their camera's lookVector. Maybe like 50 studs or so. All my code so far is in a local script inside of StarterGui. How would make this change? Any help is appreciated!

--Moving the Humanoid
    --Double Tap
enabled = true
Mouse.KeyDown:connect(function(key)
    if not enabled and clicked then
        return
    end
    if key == "w" and _G.Energy >= 25 then
    enabled = false
 
    local function onTap()
        if tick() - lastTapTime < 0.2 then
            print("double Click!")
            clicked = true
                --What happends when the user double taps
            player.Character.UpperTorso.Velocity = cam.CFrame.lookVector * Vector3.new(1,0,1) * 400 -- This is the part I want to change.
            Trail.Parent = Char.HumanoidRootPart
            local attachment0 = Instance.new("Attachment", Char.Head)
            attachment0.Name = "TrailAttachment0"
            local attachment1 = Instance.new("Attachment", Char.HumanoidRootPart)
            attachment1.Name = "TrailAttachment1"
            Trail.Attachment0 = attachment0
            Trail.Attachment1 = attachment1
            wait(0.3)
            Trail:Remove()
          --  _G.Energy = _G.Energy - 25
            wait(0.5)  
            end
        end
 
        onTap()
        lastTapTime = tick()
 
        wait(0.5)
        enabled = true
        clicked = false
    end
end)

    end
end)
 
--Repleneshing Energy
for i = 1, math.huge do
    wait(0.1)
    print(_G.Energy)
    if _G.Energy < 100 then
        _G.Energy = _G.Energy + 12.5
        print(_G.Energy)
        wait(2)
    end
end
