A stone is thrown vertically upward from the edge of a skyscraper. The initial speed of the stone at the height of the glass wall is 12.0 m/s, see Figure 1.1. Consider g= 9.80 m/s2. Find (a) the position of the stone 2.0 s after leaving the glass wall (5 pts) (b) the velocity of the stone 3.0 s after leaving the glass wall (5 pts) (c) the velocity when the stone is 4.00 m above the glass wall (5 pts) (d) the maximum height hmax​ reached by the stone ( 5pts ) (e) the acceleration of the stone at the maximum height hmax⋅​(5pts)
