An object with a mass of 4.0 Kg travels with a constant velocity of 8.5m/s northward. It is then acted on by a force of 5.0N in the direction of motion and a force of 5.9N to the south, both of which continue even after the mass comes momentarily to rest.
How far will the object travel before coming to rest?
What will be it's position 1.5s after the object comes momentarily to rest?
