An earth satellite remains in orbit at a distance of 1.7100 x 10^4 km from the center of the earth. The universal gravitational constant is 6.67 x 10^-11 N•m^2/kg^2 and the mass of the earth is 5.98 x 10^24 kg. What speed in m/s would the satellite have to maintain?

An Earth satellite has an orbital period of 5.3 h. What is its orbital radius? (ME = 5.98 x 1024 kg)

A 700 Kg satellite is placed h = 2.5 x 10^5 m above the earth. If the gravitational pull of earth is equal to the centripetal force on the satellite, determine the speed of the satellite in its orbit. Earth mass: 5.98 x 10^24 Earth radius = 6.67 x 10^ -11 Nm^2/Kg^2

(a) Evaluate the gravitational potential energy (in J) between two 6.00 kg spherical steel balls separated by a center-to-center distance of 19.0 cm. (b) Assuming that they are both initially at rest relative to each other in deep space, use conservation of energy to find how fast (in m/s) will they each be traveling upon impact. Each sphere has a radius of 5.20 cm. m/s

A satellite is traveling around a planet in a circular orbit with radius R. It moves in a constant speed of v = 1.1 × 104 m/s. The mass of the planet is M = 6.04 × 1024 kg. The mass of the satellite is m = 1.2 × 103 kg. First, find an expression for the gravitational potential energy PE in terms of G, M, m, and R.  a)Calculate the value of PE in joules.  b)Enter an expression for the total energy E of the satellite in terms of m and v.  c)Calculate the value of the total energy E in joules.

(a) Evaluate the gravitational potential energy (in J) between two 4.00 kg spherical steel balls separated by a center-to-center distance of 19.0 cm. (b) Assuming that they are both initially at rest relative to each other in deep space, use conservation of energy to find how fast (in m/s) will they each be traveling upon impact. Each sphere has a radius of 5.50 cm. m/s

Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 3.1x10^4 m/s when at a distance of 2.7x10^11 m from the center of the sun, what is its speed when at a distance of 4.7x10^10 m? Mass of the Sun is 1.99×10^30 kg. Gravitational constant is G=6.67×10^(−11) m^3 /(kg⋅s).   What is the formula?   (Answer: 75006.70209088 m/s)

A satellite with mass 848 kg is in a circular orbit with an orbital speed of 9640 m>s around the earth. What is the new orbital speed after friction from the earth’s upper atmosphere has done -7.50 * 10^9 J of work on the satellite? Does the speed increase or decrease?

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.9 x 1010 m (inside the orbit of Mercury), at which point its speed is 9.3 x 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6 x 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.) speed = m/s
