The Navstar Global Positioning System (GPS) utilizes agroup of 24 satellites orbiting the Earth. Using “triang-ulation" and signals transmitted by these satellites, theposition of a receiver on the Earth can be determined towithin an accuracy of a few centimeters. The satellite orbitsare distributed around the Earth, allowing continuousnavigational "fixes." The satellites orbit at an altitudeof approximately 11,000 nautical miles [1 nautical mile =1.852 km = 6076 ft]. (a) Determine the speed of eachsatellite. (b) Determine the period of each satellite.

A Mars observing satellite is orbiting on a circular orbit at an altitude of 1000 km above Mars’s equator. Find satellite’s acceleration and velocity as seen from a deep space communications station located on Earth’s equator, when they are on a direct line of sight (see the Fig. below). Assume for simplicity that planetary orbits and their equatorial planes are all in the plane of ecliptic (that is all, motion is in a 2D plane). Earth radius is 6300 km, Mars radius 3400 km, Mars mass 6.4x1023 kg. Assume that all circular motions are counter clockwise (i.e., orbital motions of Earth and Mars, Earth spin, and satellite orbital motion).

A satellite is in circular polar orbit around Earth at an altitude of 450 km – meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40° latitude? Earth’s radius is 6,370 km.
Suppose you could pack neutrons (mass = 1.67 × 10-27 kg) inside a small ball of radius 0.026 m in the same way as neutrons and protons are packed together in the nucleus of an atom. (a) Approximately how many neutrons would fit inside the ball? (b) A small object is placed 3.7 m from the center of the neutron-packed ball, and the ball exerts a gravitational force on it. When the object is released, what is the magnitude of the acceleration that it experiences? Ignore the gravitational force exerted on the object by the earth.
A satellite of mass 2,134 kg orbits the Earth at an altitude of 3,434 km in a circular orbit. How many hours does it take for this satellite to complete one full revolution? Mass of the Earth: kg. Mean radius of the Earth: 6370 km.
A spacecraft is in a circular orbit around the planet kerbin at an altitude of 100 km. the radium of kerbin is 600km and the planet has a mass of M = 5.29*10^22kg.

A comet goes around the sun in an elliptical orbit. At its farthest point, 415 million miles from the sun, it is traveling with a speed of 15,120 mi/h. How fast is it traveling at its closest approach to the sun, at a distance of 102 million miles?
A satellite is orbiting the earth in low orbit (160 km above the surface of the earth). If the universal gravitational constant is 6.67 x 10^-11 m^3/kg x s^2 the mass of the earth is 5.972 x 10^24 kg and the radius of the earth is 6371 km, what speed must the satellite travel in order to maintain the low earth orbit?
Could I please have some guidance on the steps for this? An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.450×105 km and the planet has a radius of 3.850×103 km and a mass of 4.90×1022 kg , how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67×10−11N·m2/kg2.
