You launched a model rocket with an initial speed of 64 feet per second and a start height of 512. After how many seconds will the rocket hit the ground?

At what time does the object hit the ground? An object is projected into the air with a path described by the quadratic function: . where h is the height above the ground in feet and t is the time in seconds since the object started along the path. What is the max height? At what time does the object hit the ground? At what time is the object at 112 ft?

A boy at a football game dropped his football 112 feet from the stands to the ground. The number of seconds, t, it took the football to reach the ground is modeled by the equation: . . How many seconds did it take the football to reach the ground? Round to the nearest tenth.
