When a falling meteoroid is at a distance above the Earth's surface of 2.3 times the Earth's radius, what is its acceleration due to the Earth's gravitation? (Units: m/s?)

106 MeV) is Extra: A very rare but occasionally observed decay of a muon µ (rest energy = into an electron e (rest energy 0.511 MeV) and a photon y (rest energy decays at rest by this mode, what is the kinetic energy of the electron and photon combined after the decay? (1M V = 10°eV = 1.6 x 10-13 J) zero). If a muon

Extra: You have two disks lying flat on ice, one has a string wrapped around the outside edge which unravels as you pull, the other has a string attached to a peg in the center. The discs have equal masses and dimensions and are initially at rest. If you start pulling both strings at the same time with the same constant force, at some time t later which of the two disks has moved further? Or have they both moved the same distance? Explain.

When a falling meteoroid is at a distance above the Earth's surface of 2.4 times the Earth's radius, what is its acceleration due to the Earth's gravitation? (Units: m/s2)

A sun rays take about 8 minutes to reach the Earth surface travelling at constant speed v= 3,0 * 10^8 m/s. How far is earth from the sun?

A satellite m = 500 kg orbits the earth at a distance d = 225km above the of the planetThe radius of the earth r_{e} = 638 * 10 ^ 6 * m and the gravitational constant G = 6.67 * 10 ^ - 11 * N * m ^ 2 / k * g ^ 2 and the Earth's mass m_{e} = 5.98 * 10 ^ 24 * kg What the speed of the satellite in m/s

When a falling meteor is at a distance 3.58times the radius of the Earth above theEarth’s surface, what is its free-fall acceleration? The acceleration of gravity is9.8 m/s squared. , the universal gravitational constant is 6.67259×10−11 N · m2/kg2 and the Earth’sradius is 6.37 × 106 m. Answer in units of m/s 2.

A spacecraft is in a circular orbit around the planet kerbin at an altitude of 100 km. the radium of kerbin is 600km and the planet has a mass of M = 5.29*10^22kg. The universal gravitational constant is G = 6.67*10^-11 Write parametric equations for the position, velocity and acceleration vectors of the spacecraft in its orbital plane.

A satellite is orbiting the earth in low orbit (160 km above the surface of the earth). If the universal gravitational constant is 6.67 x 10^-11 m^3/kg x s^2 the mass of the earth is 5.972 x 10^24 kg and the radius of the earth is 6371 km, what speed must the satellite travel in order to maintain the low earth orbit?

Use Newton’s universal gravitation formula to determine the gravitational force of attraction between the earth and the moon given: mass (moon) m(moon)=7.35 x 10^22kg the mass of the earth is m(earth)=5.98 x 10^24kg the distance between centers of the earth and moon is r=3.92 x 10^8 m use Newton gravitation equation F=G(m(1) x m(2))/r^2
