- 19. According to Isaac Newton, the value of the constant, k, in Kepler's Third Law (P2 = ka3) is dependent on which one of the following quantities for objects within the Solar System? a. The distance between the Sun and its planet. b. The mass of the planet. c. The electric charge of the Sun. d. The mass of the Sun.6. A synchronous orbit is an orbit about a planet's equator that always remains above the same spot of the planet because the synchronous orbit matches the planet's rotational period. The pilot of the Mars spacecraft (which was named Cheetah 1 and had a 9556 kg mass) asked Tarzan to calculate the altitude of a synchronous orbit so they could remain over a particular geological feature on the Martian equator. Calculate the altitude above the Martian equator using the data above and Johannes Kepler's genius.10. Use the formulas a = v2/r and v = 2πr/T to derive the following formulas: (a) centripetal acceleration in terms of v and T (but not r). (b) centripetal acceleration in terms of r and T (but not v).
