- 2. Comets travel around the Sun in highly eccentric elliptical orbits. If a comet has a speed V1 = 2.0×104 ms-1 at ri = 2.5x1011 m from the center of the Sun, what is its speed when its distance of r2 = 5.0×1010 m?C) ESA wants to send a satellite to Jupiter to investigate its internal structure and origin by measuring the atmospheric composition and temperature. The spacecraft will leave Earth from a parking orbit of radius 6578 km and arrive at Jupiter in a parking orbit of radius 75782 km. What is the total velocity change required to do this mission? How long would it take for the satellite to arrive at Jupiter?Q5, plz

- 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.Example 4. A satellite is orbiting a circular orbit at an altitude of 900 km, at which atmosphere density is 5.46 x 10-13kg/m³.
