10. Yosemite Falls in California is made of three smaller falls. The upper fall drops 1450 feet. The height h in feet of a water droplet falling from the upper fall to the next fall is modeled by h(t)=-16 t²+1450, where t is the time in seconds after the initial fall. Estimate the time it takes for the droplet to reach the next fall.
