If the Earth suddenly stopped spinning, what immediate effect would occur to objects not anchored to bedrock?

Answer

They would continue moving eastward at the previous rotational speed due to momentum

If the spin ceased instantly, everything not bolted down would keep moving eastwards at the rotational speed possessed moments before, until friction or impact stopped it.
