While training, Obi Wen uses the force to knock Anakin's lightsaber out of his hand and over a cliff overlooking the ocean. Anakin jumps in after it and his path can be modeled by h(t)=-t^{2}+12t+64h(t)=−t 2

+12t+64 where time is in seconds and height is in feet. How long until Anakin hits the water?
