Unformatted text preview: 3-1) a) Note that the mass cancels out, so that acceleration does not depend on the mass of the object: ! GMem m|asurface | = R2 e Then we have GMe g= R2 e g= ! GMe ! |asurface | = R2 e (6.67 ! 10-11 m3 / kg " s2 )(5.974 ! 1024 kg) (6.37 ! 106 m)2 g = 9.82 m/s2 b) The gravitational acceleration would be the same, g = 9.82 m/s2, since it does not depend on the mass of the object. c) Now the radius is the sum of the earth's radius and the altitude of the space station (380 km = 0.38 106 m). GM g= 2e r (6.67 ! 10-11 m3 / kg " s2 )(5.974 ! 1024 kg) g= (6.37 ! 106 m + 0.38 ! 106 m)2 g = 8.75 m/s2 3-2) 3-3) ...
