Consider a 435 satellite in a circular orbit at a distance of 3.19X10^4 above the Earth’s surface. What is the minimum amount of work W the satellite’s thrusters must do to raise the satellite to a geosynchronous orbit? Geosynchronous orbits occur at approximately 3.6X10^4 above the Earth’s surface. The radius of the Earth and the mass of the Earth are RE=6.37X10^3 and 5.97X10^24 respectively. The gravitational constant is G = 6.67X10^-11 Assume the change in mass of the satellite is...

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...

A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A 5.9010 m2 and mass m 4,800 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2 (a) What force (in N) is exerted on the sail? (Enter the magnitude.) 4.47 If you...

A satellite with mass 898 kg is in a circular orbit with an orbital speed of 5840 m/s around the earth. a) What is the new orbital speed after friction from the earth's upper atmosphere has done −7.5×10^9 J of work on the satellite? Express your answer with the appropriate units. b) Does the speed increase or decrease?

Today, the Moon’s orbit around
Earth has a semi-major axis of a=384,400 km and an orbital period
of 27.32166 days.
a. The Moon slowly moves outward due to tidal braking of the
Earth’s rotation, and at some future date the Moon will have an
orbital period of 47 days. Compute the semi-major axis of the
Moon’s orbit at this future date (express your answer in
kilometers).
semi-major axis = 5.5*10^5 km
b. Today, the Moon has an angular diameter of...

Two satellites, of masses m and 3m, respectively, are in the same circular orbit about the Earth's center, as shown in the diagram above. The Earth has mass Me and radius Re. In this orbit, which has a radius of 2Re, the satellites initially move with the same orbital speed vo but in opposite directions. photo of scenario: http://tinypic.com/view.php?pic=xkrx9u&s=9#.VxYdLMfKe8U a. Calculate the orbital speed v0 of the satellites in terms of G, Me, and Re. b. Assume that the satellites...

10) The international space station (ISS) orbits the Earth from
an altitude of 408 km.
a) Calculate the strength of Earth’s gravity on the ISS at that
altitude. (Hint: How far is the ISS from the center of mass of the
Earth?)
b) Earth’s gravity is what keeps the ISS in its orbit (which we
will assume is circular). At what speed does the ISS orbit the
Earth?
