While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 7.07 m/s. The stone s

ubsequently falls to the ground, which is 19.3 m below the point were the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s^2 for the acceleration due to gravity.

Answer:

the stone hits the gound with a speed of 20.7 m/s

Explanation:

Becuase gravity is constant we know that the initial upward velocity will be equal to the downward velocity when the stone has returned to its intal location.
