A piece of space debris is released from rest at an altitude that is two earth radii from the center of the earth. Compared to its weight on Earth, the weight of this debris is
I know the answer is "One-quarter of its weight on the surface of the earth"
but can someone explain the reasoning behind this? Preferably using words.

Major Tom orbits the planet Earth aboard a geosynchronous space station. In a geosynchronous orbit, the station stays above the same spot on the surface of the planet and orbits in time with Earth’s rotation. A) What is the space station’s orbital speed? Assume the radius is perfectly circular. B) What is the only possible radius for such an orbit? (You may calculate the radius from the center of the Earth) C) Major Tom’s weight on the surface of Earth...
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?
Please show working

Consider a Hohmann transfer from a circular parking orbit around Earth at 200 km altitude, to the Moon (distance center of mass Earth – center of mass Moon is 384,000 km; you can ignore the size of the Moon and the altitude of the target orbit around the Moon). The Moon orbits Earth in a circular orbit as well. Both orbits (parking,Moon) are coplanar. What is the velocity of the Moon,and what is the velocity of the satellite when reaching...
Question 21 5 pts A small space rock of mass m is released from rest a very long distance away ("infinity from a planet of mass M and radius R. The rock falls to the planet's surface. What is the network done on the rock by the force of gravity from the initial moment of release to just before it hits the surface of the planet? You can ignore air resistance and assume that the rock falls in along a...
In an experiment in space, one proton is held fixed and another proton is released from rest a distance of 2.50 mm away.. What is the initial acceleration of the proton after it is released. Please explain where you find the numbers to plug in the formula that is what is really confusing such as the mass and charge because it does not mention it in the question. I know were going to use F=ma and F=kq/r^2 but there are...
1. A small mass (m = 0.25 kg) is released from rest within and near the left side of a large spherical shell of material. Which direction will the small mass accelerate? left toward the center right It will not move 2. The same small mass from question #1 is now released from rest 1000 m from the center of a shell of material. The shell has a radius of 500 m and a mass of 10000 kg. A second...
How much work is necessary to bring the proton from rest infinetly far away to rest at a distance of 3m from the nucleus? I've know how to get the answer for the first part of the question which asks, " How much (mass) energy is released when a 13C nucleus combines with a proton?" which is 7.5505 MeV, but I'm not sure how to answer the energy question. I think you'd use the equation Wnc= Kf-Ki+ Uf+Ui but I...

7. A block is released from rest at point P and slides along the frictionless track shown. At point Q, its speed is: I B) 2g(h- h) C) (h. - n12g D) E) (h, -h)/29 8. A ball of mass m, at one end of a string of length L, rotates in a vertical circle just fast enough to prevent the string from going slack at the top of the circle. Assuming mechanical energy is conserved, the speed of the...
3. In interplanetary exploration, elliptical transfer orbits, like the one shown from Earth to Mars, allow space probes to reach the intended destination using a minimum of fuel. (Such orbits are called Hohmann transfer orbits.) Note: Assume the orbits of Earth and Mars about the Sun are circular with radii 1.000 AU and 1.524 AU, respectively. Ignore any effects due to the rotation of the Earth a. Describe qualitatively the maneuvers required PM TE Sun for the probe upon entering...
