As standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.87 m/s. The stone then falls to the ground that is 16.3 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? Overlook air resistance and take g = 9.81 m/s2.
