Question

Solve both parts 

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.29 m/s. The stone subsequently falls to the ground, which is 11.1 m below the point where the stone leaves his hand. Ignore air resistance and use g = 9.81 m/s² for the acceleration due to gravity. At what speed v does the stone impact the ground? How much time t does the stone spend in the air? U = 16.02 1.64 t= Incorrect m/s
