A skydiver is jumping from a plane at an altitude of 13,000 ft. The equation h(t)=-16t^2+13,000 represents the height h after t seconds. In order to safely land, the skydiver must deploy their parachute at an altitude of 2,500 ft. 1. How many second of free fall will the skydiver experience before deploying their parachute
2. Sketch a graph that represents the skydivers height over time. Label key events of the skydivers fall on the graph and each axis.
