Well, you can either decide for yourself that you roll a dice determining how far (1d12 seems appropriate) or you can think up what makes sense in the situation. Since the rule text doesn't describe anything particular you can't give a player a specific answer, unless you make it up yourself.

Bear in mind what the spell description says (my emphasis):
So your spoon is likely to be resting on a table - most likely wood, so it has reasonable friction - but the spoon itself is less than 1 ENC. In such a circumstance I'd rule that the spoon can be pushed or pulled 1 metre per point of Magnitude of the spell.
Larger items you'll need to adjudicate depending on the item (does it have wheels? Is it dense?) and its surface (low or high friction? Muddy or dry? Slippery?). There are too many variables to be able to give a series of precise rulings.
There's always the option of calculating how far it can throw things in terms of energy.
Given the formula for the spell, we could assume the energy it exerts is 9.82N/kg*1m*5kg ; Assuming it will move an object at the maximum of it's siz requirement 1m, directly up, when used from directly below. This gives us a base value of 49.1J per point of magnitude.
Then you could calculate the speed at which it fires the object from Ekin=m/2*v^2 , plot a positioning function and see when it stops to move.
Then if you have a surface from which it moves, you'll have to add the deceleration that surface causes on the object, from a various number of formula depending on whether it moves across a liquid, a solid material or a gas.
So all I can say is, it's up to the DM. But pushing at a door, would probably close it. And pulling a key would probably move it towards you some amount of meters.
This would need an Errata I agree though, the fact that it says the caster has no control also means the DM has no idea, which is pretty silly.
