Question

A satellite is in a circular orbit around the Earth at an
altitude of 3.84 10^{6} m.

(a) Find the period of the orbit. (*Hint*: Modify
Kepler's third law so it is suitable for objects orbiting the Earth
rather than the Sun. The radius of the Earth is
6.38 10^{6} m, and the mass of the Earth is
5.98 10^{24} kg.)

h

(b) Find the speed of the satellite.

km/s

A satellite of mass 1525 kg is in circular orbit around Earth.
The radius of the orbit of the satellite is equal to 1.5 times the
radius of Earth (RE = 6.378*106 m, ME = 5.98*1024 kg, G =
6.67*10-11 Nm2/kg2). (a) Find the orbital period of the satellite?
(b) Find the orbital (tangential) velocity of the
satellite. (c) Find the total energy of the
satellite?

A satellite in a circular orbit around the earth with a radius
1.019 times the mean radius of the earth is hit by an incoming
meteorite. A large fragment (m = 69.0 kg) is ejected in the
backwards direction so that it is stationary with respect to the
earth and falls directly to the ground. Its speed just before it
hits the ground is 367.0 m/s.
a)Find the total work done by gravity on the satellite fragment.
RE 6.37·103 km;...

1. A satellite is in a circular orbit about the earth (ME = 5.98
x 1024 kg). The period of the satellite is 2.35 x 104 s. What is
the speed at which the satellite travels?
2. Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 545 km above the earth’s
surface, while that for satellite B is at a height of 787 km. Find

A satellite is in a circular orbit around Earth with an altitude
equal to 2.50 times Earth's radius. What is the magnitude of the
centripetal acceleration of this satellite? [Hint: you do not need
to look up Earth's mass or radius to solve this one.]
can you solve this?

A satellite orbits the Earth uniformly in a circular orbit with
a velocity of magnitude 4.00 km/s. Use Newton's gravitation force
as the force in Newton's Law of Acceleration, using also the
centripetal acceleration . Solve for radius r of the satellite's
orbit in terms of v . (a) Find then the altitude of the satellite
above the surface of the Earth. Earth's mass and radius are 5.9810
kg and 6.3810 km. (b) Find the time it takes the satellite...

A 345 kg satellite is orbiting on a circular orbit 8955 km above
the Earth's surface. What is the gravitational acceleration at the
location of the satellite? (The mass of the Earth is
5.97×1024 kg, and the radius of the Earth is 6370
km.)?
