A toy rocket blasts straight up off the gound with an initial velocity of 50 ft/s. How long will the rocket remain in the air? Use the formula h=-16t^2+50t, where h is the height of the rocket in feet and t is the time in seconds after liftoff. Assume no air resistance, and that the rocket has no propelling force after liftoff. Round your answer to the nearest tenth.
