Explanation / Answer

Both stones have the same horizontal speed. The horizontal distance traveled by one of the stones is given by the product of the x component of its velocity and the time the stone spends in the air. From Part A, the time spent in the air by the stone that is thrown upward is greater than that spent in the air by the stone thrown downward. Therefore, the stone that is thrown upward travels farther in the horizontal direction
