36. Sample Problem, continued Chapter 7 Use Table 1 in the textbook to find the values for the radius ( r 2 ) and mass ( m ) of Venus. r 2 = 6.05  10 6 m m = 4.87  10 24 kg Find r by adding the distance between the spacecraft and Venus’s surface ( r 1 ) to Venus’s radius ( r 2 ). r = r 1 + r 2 r = 3.61  10 5 m + 6.05  10 6 m = 6.41  10 6 m Section 3 Motion in Space
