According to Lunar Laser Ranging experiment the average distance Lm from the Earth to the Moon is approximately 3.97 x 105 km. The Moon
orbits the Earth and completes one revolution relative to the stars in approximately 27.5 days (a sidereal month).
Calculate the orbital velocity of the Moon in m/s.
In this problem you will measure the gravitational constant in a series of “observational experiments,” making use of Newton’s law of gravitation and second law of motion as well as Kepler’s third law of planetary motion
Suppose a rocket is launched as described in part (d) with an initial speed of vi = 494 m/s and attains a peak altitude of H = 12.7 km above the surface of Earth. Taking ME = 5.95×1024 kg and Ri = 6.41×106 m, what is the measured value of the gravitational constant, in units of N⋅m2/kg2?
GPS (Global Positioning System) satellites orbit at
an altitude of 2.7x10^7m.
