Question
  1. A stone is thrown from the top of a building with an initial velocity of 20.0 m/s straight upward, at an initial height of 50.0 m above the ground. The stone just misses the edge of the roof on the its way down. Determine

    (d) the time needed for the stone to reach the ground.

      Ans: t = 5.83 s

    (e) the velocity and position of the stone at t = 5.00s

      Ans: v = -29 m/s & y = -22.5 m
