Explanation:

According to Newton's first law of motion, 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. Since nothing changes for the ball on the icy surface, there is no unbalanced force to make it move.

The ball will remain motionless
