You throw a ball vertically upward from the roof of a tall building. The ball leaves your hand at a
point even with the roof railing with an upward speed of 15.0 m/s; the ball is then in free fall. On its
way back down, it just misses the railing. Find (a) the ball’s position and velocity 1.00 s and 4.00 s
after leaving your hand; (b) the ball’s velocity when it is 5.00 m above the railing; (c) the maximum
height reached; (d) the ball’s acceleration when it is at its maximum height.
