A spacecraft is coasting toward Mars. The mass of Mars is 6.4 ×
1023 kg and its radius is 3400 km (3.4 × 106
m). When the spacecraft is 8900 km (8.9 × 106 m) from
the center of Mars, the spacecraft's speed is 2250 m/s. Later, when
the spacecraft is 5200 km (5.2 × 106 m) from the center
of Mars, what is its speed? Assume that the effects of Mars's two
tiny moons, the other planets, and the...
