Question: You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 47° from the edge of the building with an initial velocity of15 m/s and lands 69 meters away from the wall.
Question I: How tall is the building that the child is standing on?
Please also explain, thank you in advance.
