A 2.00 kg stone is sliding to the right on a frictionless horizontal surface at 5.00 m/s when it is suddenly struck by an object that exerts a large horizontal force on it for a short period of time.

Just after the force stops acting, find the magnitude of the stone's velocity if the force acts to the right and find the magnitude of the stone's velocity if the force acts to the left.
