Problem 13.63 The moon's radius is 1738 km. The magnitude of the acceleration due to gravity of the moon at a distances from the center of the moon is 4.89 1012 $2 m/s. Suppose that a spacecraft is launched straight up from the moon's surface with a velocity of 2000 m/s. (a) What will the magnitude of its velocity be when it is 1000 km above the surface of the moon? (b) What maximum height above the moon's surface will it reach? Problem 13.63 The moon's radius is 1738 km.
