Help with linear velocity

[supercronter4 (Lezrus)]

hi I need help with this, when the humanoid root part is anchored and unanchored there’s a bit of shake when applying linear velocity

sd

this is how the linear velocity is applied

local VY_Axis = Instance.new("LinearVelocity", self)
	local a0 = Instance.new("Attachment", self)
	a0.Name = "ADJ"
	
	VY_Axis.MaxForce = math.huge
	VY_Axis.Attachment0 = a0
	VY_Axis.VectorVelocity = Vector3.new(0, 70, 0)
	
	wait(0.05)
	VY_Axis:Destroy()
	a0:Destroy()
