The Moon orbits Earth in a nearly circular orbit that lasts 27.32 days.
1) Determine the distance from the surface of the Moon to the surface of Earth in Mm. (Express your answer to three significant figures.)
A planet orbits a star with an orbital radius of 1 AU. The star has a mass that is 1.60 times our own Sun's mass.
2) Determine the time for one revolution of the planet around the star in years. (Express your answer to three significant figures.)

-The Moon orbits the Earth in an approximately circular path.
The position of the Moon as a function of time is given by
x(t)
=
r cos(ωt)
y(t)
=
r sin(ωt),
where r = 3.84 108 m and
ω = 2.46 10-6 radians/s. What is the
average velocity of the Moon measured over the interval from
t = 0 to t = 3.35 days? Find its magnitude, in
m/s, and find its direction, given as an angle measured
counterclockwise from the positive...

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 555 km above the earth’s
surface, while that for satellite B is at a height of 778 km. Find
the orbital speed for (a) satellite A and (b) satellite B.

The Moon orbits Earth in an average of p = 27.3 days at an
average distance of a =384,000 kilometers. Using Newton’s version
of Kepler’s third law determine the mass of Earth. You may neglect
the mass of the Moon in comparison to the mass of Earth.

Consider a Hohmann transfer orbit between Earth and Saturn (you
may assume circular orbits). Describe the orbit in terms of its
semi-major axis, period, and distance from the sun at aphelion and
perihelion.

An asteroid is discovered to have a tiny moon that orbits it in
a circular path at a distance of 151 km and with a period of 43.0
h. The asteroid is roughly spherical (unusual for such a small
body) with a radius of 15.9 km.
a) Find the acceleration of gravity at the surface of the
asteroid.
b) Find the escape velocity from the asteroid.

a) Jupiter's satellite orbits the planet on a nearly circular
path with a radius of 420,000 km and completes its orbit every
1.769 days. Use Newton's universal law of gravitation to find the
mass of Jupiter.
b) Knowing Jupiter's mass, and that it orbits the Sun on the
average (it has an elliptical orbit with an eccentricity of 0.05)
at 7.8×108 km from the Sun in 11.86 years, what is its
angular momentum?
c) Compare Jupiter's orbital angular momentum to...

1.Consider a satellite of the earth in a circular orbit of
radius R. Let M and m be the mass of the earth and that of the
satellite, respectively. Show that the centripetal acceleration of
the satellite is aR =
-(v^2/R)*(r/r) where v = |v| is
the magnitude of the velocity V and
r/r is a unit vector in the radial direction.
2.Using Newton's second low of motion and the law of universal
gravitation, determine the speed v=|V| and the...

A satellite is placed in an elongated elliptical (not circular)
orbit around the Earth. At the point in its orbit where it is
closest to the Earth, it is a distance of 1.00 × 10^6
m from the surface (not the center) of the Earth,
and is moving at a velocity of 5.14 km/s. At the
point in its orbit when it is furthest from the Earth it is a
distance of 2.00×10^6 m from the surface of the
Earth....

Q10. Assume that the Earth is orbiting the sun in a perfectly
circular orbit. If the Earth is hit by a huge meteorite but its
orbiting angular momentum is not changed (this can be the case if
the hit is along the radial direction of the orbit), what would be
the change in Earth’s orbit?
A. No change
B. Earth would move in a circular orbit with a larger radius
C. Earth would move in a circular orbit with a...
