Answer: see below
Explanation:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Friction opposes relative motion. In its absence, a moving object will not stop.
2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.
3) No they are not the same, as one has friction and the other has no friction.
