Suppose that an astronaut throws a rock in outer space at a location far from significant influences of gravity and air resistance. one would expect that the rock would a. eventually stop since all objects ultimately "lose their steam"b. eventually stop as its inertia slowly becomes used upc. continue in motion with the same speed and directiond. either a, b,c… depending on whether the astronaut continues to push it.

c

Explanation:

The Newton's first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In outer space, and particularly in a location far from influences of gravity (and any other forces such as air resistamce) no external force is acting upon the rock, so it will continue its motion in a straight line with the same speed and the initial direction.

However if the astronaut continues to push it, he will apply a force to the rock, and the motion of tghe rock will be determined by the Newton's second law and the force the astronaut is extering to it
