How do I project an entity forward and set the velocity back the opposite direction?

Basically I just want to throw something out, and have it come back after a bit. Here's what i used:

[lua]
function ENT:Throw()
local phys = self:GetPhysicsObject()
if IsValid(phys) && IsValid(self:GetOwner()) then
phys:ApplyForceCenter(self:GetOwner():GetAimVector() * self.Speed)
end
end

function ENT:Return()
local phys = self:GetPhysicsObject()
if IsValid(phys) then
phys:SetVelocity(Vector(0,0,0))

phys:ApplyForceCenter( self:LocalToWorld(self:GetOwner():GetAimVector()) * self.Speed )
end
end
[/lua]

The throw works, but the return isn't.

"Doesn't work" isn't very descriptive.

Why are you converting it into local coordinates? And why are you basing it on the user's aimvector?
If you want the ball to return it should be

function ENT:Return()
	local phys = self:GetPhysicsObject()
	if IsValid(phys) then
		phys:SetVelocity(Vector(0,0,0))
		local direction = self:GetOwner():EyePos() - self:GetPos()
                direction:Normalize()
		phys:ApplyForceCenter( direction * self.Speed )
	end
end

This could work, not entirely sure though
