A vertical rectangle representing a building of height labeled \(45\text{ m}\) stands on a flat horizontal ground line. At the top right corner of the building, a small solid circle representing a stone is shown with a horizontal rightward arrow labeled \(v_0\). A dashed downward-curving parabolic arc extends from the stone to the ground. A horizontal dimension line between the base of the building and the landing point on the ground is labeled \(60\text{ m}\). No other labels, lines, text, or axes appear.
Trajectory of the stone launched from the building.
A stone is launched horizontally from the top of a \(45\text{ m}\) tall building and lands on level ground at a horizontal distance of \(60\text{ m}\) from the base of the building. Neglecting air resistance and using \(g = 10\text{ m/s}^2\), what is the initial horizontal launch speed of the stone?
