Explanation:
Replace h with 0. Solve for t.
![h = -16t^2 + 26\\\\0 = -16t^2 + 26\\\\16t^2 = 26\\\\t^2 = 26/16\\\\t^2 = 1.625\\\\t = \sqrt{1.625}\\\\t \approx 1.2748\\\\t \approx 1.3\\\\](https://tex.z-dn.net/?f=h%20%3D%20-16t%5E2%20%2B%2026%5C%5C%5C%5C0%20%3D%20-16t%5E2%20%2B%2026%5C%5C%5C%5C16t%5E2%20%3D%2026%5C%5C%5C%5Ct%5E2%20%3D%2026%2F16%5C%5C%5C%5Ct%5E2%20%3D%201.625%5C%5C%5C%5Ct%20%3D%20%5Csqrt%7B1.625%7D%5C%5C%5C%5Ct%20%5Capprox%201.2748%5C%5C%5C%5Ct%20%5Capprox%201.3%5C%5C%5C%5C)
