3. Mars has two moons, Deimos and Phobos, traveling in circular orbits (to a good approximation) Deimos takes 30.3 hours to orbit Mars (i.e. 30.3 hours per full rotation around the planet) and travels with a speed of 1.35 km/s. [16 points] a) What is the radius of Deimos' orbit around Mars? [9] Hint: First find the circumference of Deimos' orbit. Then infer the radius from that.] b) What is the magnitude and direction of Deimos' acceleration? [7]
Two moons orbit a planet in circular orbits. The first has an orbital radius of r1 and a period of T1. The second has twice the orbit radius as the first. Find the period of the second planet. 4.8T1 1.4T1 2.8T1 3.8T1

with an atmospheric detection satellite orbiting in a circular orbit at a radius R rotte art conter where it orbits with a constant speed V. If they want the next mation of satellites to orbit at a speed of V/2, how far from the earth's center they have those satellites orbit?
6 of 13 Properties of Circular Orbits Constants Find the orbital speed of a satelite in a circular orbit of radius R around a planet of mass M. Express the orbital speed in terms of G, M, and R. View Available Hint(s) Learning Goal: To find some of the parameters characterizing an object moving in a circular orbit. The motivation for Isaac Newton to discover his laws of motion was to explain the properties of planetary orbits that were observed...
Two satellites, A and B, are in different circular orbits about the earth. The orbital speed of satellite A is sixty-seven times that of satellite B. Find the ratio (TA/Tg) of the periods of the satellites.
Consider a Star with three planets orbiting it with circular orbits and constant orbital speeds. The planets all have the same mass, but different orbital radio (r for m1, 2r for m2, and 3r for m3) and different speeds. A.) If the relationships of the centripetal forces are known to be F1<F2<F3, then what is the relationship between the velocities? I’m looking for the form (Av1<Bv2<Cv3). Is it, 1v1<4v2<16v3? B.) If the relationship of the periods are known to...
10. Two satellites are in circular orbits around a planet that has radius 9.00 × 106 m. One satellite has mass 68.0 kg, orbital radius 5.00 × 107 m, and orbital speed 4800 m/s. The second satellite has mass 84.0 kg and orbital radius 3.00 × 107 m. what is the orbital spced of this second satel!lite? 1 International Space Station. The International Space Station makes 15.65 revolutions per day in its orbit around the earth. Assuming a circular orbit,...
A planet has two small satellites in circular orbits around the planet. The first satellite has a period 12.0 hours and an orbital radius 6.00 x 107. The second planet has a period of 16.0 hours. What is the orbital radius of the second satellite?
Two particles moving under the influence of their mutual gravitational force describe circular orbits about one another with period r. a. Use Newton's second law to find an expression for ro, the radius of the particles' orbit around each other in terms of r b. Write an expression for the total energy of the system. (You don't have to use your answer to part a; keep it as ro.) c. Both particles are pushed inward such that their separation is...
Let a satellite orbits a planet of mass M at circular orbit of radius R. Find the orbital period T. Express your answer in terms of G, M, R, and π If the mass of the planet is 5.98 x 1024 kg, calculate the ratio of T2 to R3.
