The Lunar Module could make a safe landing if the vertical velocity at landing was 3.0 m/s or less. Find the equation for greatest height h where the Lander could shut off its engines and land safely, if at that h it has a vertical velocity v. Find the height h if vertical velocityis a) zero; b) 2m/s downward, c) 2m/s upward. The acceleration due to gravity at the surface of the moon is 1.62 m/s^2 .
