reference frame?

A satellite of mass m = 2.00 ×103 kg is launched into a
circular orbit of orbital period T = 4.00 hours. Newton's
gravitational constant is G = 6.67 ×10−11 N∙m2/kg2, and
the mass and radius of the Earth are respectively M⨁ =
5.97 ×1024 kg and r⨁ = 6.37 ×106 m. Answer the following
questions.
What is the total mechanical energy (kinetic energy + potential
energy) of the satellite in orbit? Take the gravitational potential
energy of the satellite...

In order better to map the surface features of the Moon, a 393
kg imaging satellite is put into circular orbit around the Moon at
an altitude of 149 km. Calculate the satellite's kinetic energy,
gravitational potential energy, and total orbital energy. The
radius and mass of the Moon are 1740 km and 7.36×1022 kg.

The Earth (mass = 6.0 x 1024 kg) and the Moon (mass = 7.3 x 1022
kg) are separated by an average distance of about 3.8 x 105 km.

B. 7.7 x 1031 N
C. 2.0 x 1026 N
D. 2.0 x 1020 N

n order better to map the surface features of the Moon, a 311 kg
imaging satellite is put into circular orbit around the Moon at an
altitude of 133 km. Calculate the satellite's kinetic energy,
gravitational potential energy, and total orbital energy. The
radius and mass of the Moon are 1740 km and 7.36×1022 kg.

A satellite of mass 3.00 x 104 kg is placed in orbit
around Jupiter. The mass of Jupiter is 2.90 x 1027 kg.
The distance between the satellite and the centre of Jupiter is
9.24 x 107 m.
Determine the force of gravitational attraction between the
satellite and Jupiter.
One of the moons of Jupiter is Io. The distance between the
centre of Jupiter and the centre of Io is 5.22 x 108 m.
If the force of gravitational attraction...

3. The Moon orbits the Earth every 27.3 days with a near
circular orbit of 385,000 km. What is the mass of the Earth based
on this information? What is the kinetic energy of the moon? (mass
of the Moon = 7.35 x 1022 kg) What is the potential
energy of the moon? What is the acceleration due to gravity
(towards the Earth) at the distance of the Moon?

The centers of the moon and the Earth are separated by 3.84 x
108 m. The moon has a mass of 7.34 x 1022 kg. The mass of the earth
is 5.97 x 1024 kg.
Given:
a. Find the gravitational attraction between the earth and
moon.
b. Find the acceleration of the moon toward the earth.
c. Find the speed of the moon in its orbit.
d. Find the circumference of the orbit.
e. Calculate the time it takes the...

Calculate the force of gravity between the Earth and the Moon.
The mass of the Earth is 6.0 x 1024 kg and the mass of
the Moon is 7.4 x 1022 kg. The average distance between
the Earth and the Moon is 3.8 x 108 m. (G = 6.67 x 10-11
Nm2/kg2 ) Show your
work.
