106. Projectile A model rocket will be launched from a hill 80 feet above sea level. The launch site is next to the ocean (sea level), and the rocket will fall into the ocean. The rocket's distance, s, above sea level at any time, f. is found by the equation s(r) - -16r² + 64r + 80. Find the time it takes for the rocket to strike the ocean.
