Scene(6)

Kennedy Space Center Florida (USA)

NASA was rocked when the entire facility was hit with a bioweapon. Calcuu Paraboloid used the opportunity to steal a space shuttle. Presumably, this is the final piece of his world conquering device. The final note was left on the stall of a NASA restroom. The final text message followed

Before you know it, the Mathemagicians are finally going to conquer the world! For my last puzzle, a Mars Rover baseball toss problem!

(Vertical Motion Equations: The height H of an object t seconds after it is propelled upward with

an initial velocity v represented by H = -1⁄2 gt2 + vt + h, where g is the gravitational pull and h is the initial height.)

Suppose a NASA rover on Mars, throws a baseball upward with an initial velocity of 10 meters per second, letting go of the ball 2 meters above the ground. Since the gravity stuff works different on Mars it will take longer for the ball to land. How much longer will the ball stay in the air on Mars? The answer to this question rounded to the nearest tenth is equal to A.
