A satellite describes an elliptic orbit of minimum altitude 606 km above the surface of the earth. The semimajor and semiminor axes are 17 440 km and 13 950 km, respectively. Knowing that the speed of the satellite at point C is 4.78 km/s, determine (a) the speed at point A, the perigee, (b) the speed at point B, the apogee.

A satellite of mass m= 100 kg is in a circular orbit at a height h = R above the surface of the earth where R is the radius of the earth. Find (a) the acceleration due to gravity at any point on the path of the satellite, (b) the gravitational force on the satellite and (c) the centripetal force on the satellite.

The spaceship Palomino approaches star XYZ to study it by going into a circular orbit of radius 1.0·107 km. All that is known initially is that a planet orbits this star at a distance of 1.86·108 km taking a time of 271 Earth-days to make one full orbit. At what speed should the ship orbit the star at? What is the gravitational acceleration on the Palomino due to this star's gravity? (c) What is the ratio of the mass of star XYZ with that of the Sun? (MSun = 1.987·1030 kg)

The maximum distance of the earth from the sun is 9.3 x 107 miles. The minimum distance is 9.1 x 107. The sun is at one focus of the elliptical orbit. Find the distance from the sun to the other foci of the ellipse.
