How much work is required to lift a 700-kg satellite to an altitude of
m above the surface of the Earth? The gravitational
force is , where is the mass of the Earth,
is the mass of the satellite, and is the distance
between the satellite and the Earth's center. The radius of the
Earth is m,
its mass is kg, and in these units the
gravitational constant, , is

Work =
(include units; for this problem assume all given
constants are accurate to many significant figures.)
