A 270 kg satellite is orbiting on a circular orbit 6180 km above the Earth's surface. Determine the speed of the satellite. (The mass of the Earth is 5.97×1024 kg, and the radius of the Earth is 6370 km.)
Suppose a satellite was orbiting the Earth just above the surface. What is its centripetal acceleration? Smaller thang Equal to 3 Larger than Impossible to say without knowing the mass A hypothetical planet has a mass of half that of the Earth and a radius of twice that of the Earth. What is the acceleration due to gravity on the planet in terms of the acceleration due to gravity at the Earth? The acceleration of gravity on the Moon is...

1) An astronaut is orbiting the Earth preparing to repair a satellite. The satellite is in a circular orbit 600 km above the Earth's surface, where the free-fall acceleration is 8.20 m/s2. Take the radius of the Earth as 6400 km. a. Determine the speed of the satellite. Express your answer in meters per second. b. Determine the time interval required to complete one orbit around the Earth. Express your answers in minutes 2) The pilot of an airplane notes that the compass indicates...
A satellite is at an altitude of 852 kilometers above the Earth's surface. The mass of Earth is 5.972 x 10^24 kg and the radius of Earth is 6.378 * 10^6 m. (1) What is the acceleration due to gravity in the orbit? (2) What is the orbital velocity and period of the orbit? (3) Derive the equation for the escape velocity of the orbit and provide the numerical value.
7. An antenna on the Earth's surface sends a signal as a plane-wave to a satellite orbiting the Earth at the geostationary orbit. Assume the antenna on the satellite is A m2 across. Assuming (though incorrect) the Earth's atmosphere and outer space both to be a lossless media, what is the expression of the ratio of the power transmitted versus power received in dB? Assuming the Earth's atmosphere and outer space together present an average attenuation, what does the ratio...
A satellite orbits the earth at a distance of 10,000 miles from the earth's center. At this distance the force of gravity on the satellite is 139 lbs. What would the force on the satellite be if the distance were 5,000 miles instead?
A satellite is orbiting the Earth at a distance of 50’000 km above sea level. (a) What is the gravitational acceleration at this altitude? (15 pts) (b) What is the speed of the satellite along its circular orbit?

2. Consider a system consisting of the Sun, Earth, and a satellite in a circular orbit about the Earth. (a) Plot the gravitational acceleration of the satellite due to Earth's gravity as a function of the altitude of the satellite as measured from the surface of the Earth. Scale your plot so that the altitude goes from 0 km to 104 km. (b) Assume that the satellite instantaneously lies on the line between the Earth and the Sun. Make two...
