A soccer ball sits at rest on the ground, a perpendicular dis- tance x = 7.0 m away from the side of a building. The roof of the building is located y = 22 m above the ground. The ball is kicked into the air and directly toward the building, and it lands on the roof at the peak of its trajectory. What was the horizontal component of the balls initial velocity, vxi? For the limit check, investigate what happens to vxi if the building is extremely short (i.e.,y - > 0).
