Part A

The moon's radius is $1738km.$ The magnitude of the acceleration

due to gravity of the moon at a distance $s$ from the center of the

moon is

$\frac{4\mathrm{.}89{10}^{12}}{s^2}\frac{m}{s^2}.$

Suppose that a spacecraft is launched straight up from the

moon's surface with a velocity of $1900\frac{m}{s}.$

What will the magnitude of its velocity be when it is $1000km$ above the surface of the moon?
