Suppose that an astronaut throws a baseball in outer space at a location far from significant influences of gravity and air resistance. One would expect that the baseball would ____.
eventually stop since all objects ultimately "lose their steam"
eventually stop as its inertia slowly becomes used up
continue in motion with the same speed and direction
