QUESTION:
Use the results of Example 13.5 (Section 13.3) to calculate the escape speed for a spacecraft (a) from the surface of Mars and (b) from the surface of Jupiter. Use the data in Appendix F. (c) Why is the escape speed for a spacecraft independent of the spacecraft’s mass?
ANSWER:Step 1 of 3 a)The escape speed is , v = 2 GMm Rm 11 2 2 23 = 2×6.673×10 N.m /kg ×6.42×10 kg 3.4×10 m 3 = 5.02 × 10 m/s
