Former MLB pitcher Nolan Ryan was once recorded throwing a fastball at 100.9 mph (148 ft/s). If Nolan Ryan were to throw this high-speed pitch straight up from an initial height of 7.8 ft, how long would it remain in the air, ignoring air resistance? Use the formula 2003-19-06-00-00_files/i0120000.jpg, where h is the height of the ball in feet and t is the time in seconds since it is pitched. Round your answer to the nearest tenth.
