The stone falls vertically from the roof of a tall building with an initial velocity 9,2 m/s. After 2,9 s, the stone will reach the ground. Assuming g = 10 m/s?, determine instantaneous velocity of the stone (in m/s) at the time it incidents to the ground.The stone falls vertically from the roof of a tall building with an initial velocity 9,2 m/s.
