A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of $38\mathrm{.}0$ above the horizontal. The glider has mass $9\mathrm{.}00102$ kgkg$.$ The spring has $650$ N$/$mN$/$m and negligible mass. When the spring is released, the glider travels a maximum distance of $1\mathrm{.}60$ mm along the air track before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring.
