- 5) Titan is the largest moon of Saturn, and the only moon in the solar system known to have a substantial atmosphere. Its radius is easily measured to be 2570km. Since it doesn't have a satellite itself it's not obvious to us how we could determine its mass. Suppose an astronaut of mass 60kg visits and finds her weight to be 81N. What is Titan's mass?The space station Babylon 5 has a diameter of 1 miles, and rotates around its long axis to produce artificial gravity for its inhabitants. It completes 1.1 revolutions/min. Calculate the effective gravitational strength at the outer rim of the station, in units of g. (Use g = 9.81 m/s²)The acceleration of gravity is 9 m/s² at the surface of a planet of radius R=10°m. A satellite is to be launched from this planet into a circular orbit of radius 4R. (Probs. 8&9) 8. Find a value for the speed of this satellite when it is in this orbit. 9. Find the value of the initial velocity vo at which this satellite must be launched from the surface of the planet so that it reaches this orbit.
