Given: mM = 3.18 x 1023kg

            mV = 4.88 x 1024kg

            RM = 2.43 x 106m

            RV = 6.06 x 106m

(a) Find:  gM - ?

gM = G mM/RM2     (see Exercise 12-2 on pages 353-354)

gM = (6.67 x 10-11 N-m2/kg2)(3.18 x 1023kg) /(2.43 x 106m)2  = 3.59 m/s2

(a) Find:  gV - ?

gV = G mV/RV2   

gV = (6.67 x 10-11 N-m2/kg2)(4.88 x 1024kg) /(6.06 x 106m)2  = 8.86 m/s2
