- 2. Saturn rotates every 645 min (just under 11 h) and has a mass of 5.69 X 1026 kg. Suppose that scientists have placed a 1750 kg synchronous satellite in orbit around Saturn that has the same period as Saturn. (a) Calculate the radius at which that the synchronous satellite must orbit around Saturn. (b) Calculate the energy of placement of this 1750 kg synchronous satellite. (c) Calculate the orbital kinetic energy of this synchronous satellite (d) Calculate the orbital speed of this synchronous satellite.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?7
- #8610). Two spheres are placed 2m apart. They are fixed in place so that they cannot move. Someone takes a third object and slowly move it into place near them, as shown in the figure. M1 = 500 kg, M2 = 200 kg, and M3 = 100 kg.a). What speed would the third sphere (M3) need to be given to escape from the gravitational effects of the other two spheres?b). Once the third object is in place, what is the net force (magnitude and direction) on the third object?1. Three masses are located in the vertices of an equilateral triangle. Calculate the magnitude and direction of the gravitational force on the mass m,. Given: m, = 38 kg, m: = 340 kg, m, = 340 kg, r = 38 m. G = 6.674x10-11 N-m/kg. mg

The distance between the person and the earth is always measured from the center of the Earth. (Use G, Mg and Refrom the question #1)3. You are a person with incredible arm strength. You throw a ball of mass m = 2 kg horizontally with initialy velocity vo. (a) How quickly would you have to throw the ball so that the ball enters a perfectly circular orbit around Earth? (Assume your height is much less than Earth's radius). (b) How long would the ball take to complete one orbit? (c) Let's say you throw the ball with 1.2x the speed found in (a). What is the semi-major axis of the new elliptical orbit of the ball? (d) How long would it take for the ball to complete its new orbital jour- ney?An intergalactic spaceship arrives at a distant planet that rotates on its axis with a period of T = 31 hours. The mass of the planet is M = 2.1 • 1025 kg. The spaceship enters a circular orbit with an orbital period that is equal to the planet's period for the rotation about its axis, T. a. Enter an expression for the radius of the spaceship’s orbit. b. Calculate the orbital radius in meters.

Hint: use a system of equations based on conservation of energy and angular momentum.4. An earth satellite is observed at perigee to be 250 km above the earth's surface and traveling at about 8500m/s. Find the eccentricity of its orbit and its height above the earth at apogee. Earth radius is 6.4-10 m, G-M/R = g.#7
