While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.07 m/s. The stone
subsequently falls to the ground, which is 18.1 m below the point where the stone leaves his hand.
At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s² for the acceleration due to gravity.

How much time is the stone in the air?
