A bottle rocket is launched from the top of an 11 foot platform. The path of the modeled using the function H(t) = -2t2 + 20t + 11, where t is the time in seconds, and H
represents the height of the rocket. Using your quadratic formula, find to the nearest tenth of a
second, the time when the rocket hits the ground. Show all work.
