An astronaut on the Moon throws a baseball upward with an initial velocity of 10 meters per second, letting go of the baseball 2 meter above the ground. The equation of the baseball pathway can be modeled by h=-0.8t^2+10t+2. The same experiment is done on Earth, in which the pathway is modeled by the equation h=-4.9t^2+10t+2. How much longer would the ball stay in the air on the Moon compared to on Earth
