A block is acted upon by a 5 N force causing it to accelerate on a horizontal plane. While the block is in motion, it is acted upon by an equal and opposite force. Describe the subsequent motion of the block   It slows down, stops momentarily, then proceeds to move in the opposite direction   It still moves in the original direction with the constant acceleration which is less than the original   It still moves in the original direction but with constant velocity   It slows down constantly then stops   It stops abruptly when the second force is applied
