Answer #1

a) For a satellite to be in a circular orbit 850 km above the
surface of the earth, what orbital speed must it be given?
b) What is the period of the orbit (in hours)?

A satellite is in circular orbit at an altitude of 1500 km above
the surface of a nonrotating planet with an orbital speed of 3.4
km/s. The minimum speed needed to escape from the surface of the
planet is 8 km/s, and G = 6.67 × 10-11 N ·
m2/kg2. The orbital period of the satellite
is closest to
A)59 min.
B)45 min.
C)72 min.
D)65 min.
E)52 min.

A satellite is in circular orbit at an altitude of 1800 km above
the surface of a nonrotating planet with an orbital speed of 3.7
km/s. The minimum speed needed to escape from the surface of the
planet is 8.4 km/s, and G = 6.67 × 10-11 N ·
m2/kg2. The orbital period of the satellite
is closest to
59 min.
83 min.
75 min.
67 min.
51 min.

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
the orbital speed for (a)...

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 406 km above the earth's
surface, while that for satellite B is at a height of 904 km. Find
the orbital speed for satellite A and satellite B.

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 556 km above the earth’s
surface, while that for satellite B is at a height of 888 km. Find
the orbital speed for (a) satellite A and
(b) satellite B.

A 160 kg satellite is orbiting on a circular orbit 7655 km above
the Earth's surface. Determine the speed of the satellite. (The
mass of the Earth is 5.97×1024
kg, and the radius of the Earth is 6370 km.)
(in km/s)

a) What linear speed must an Earth satellite have to be in a
circular orbit at an altitude of 141 km above Earth's surface? (b)
What is the period of revolution?

A satellite is orbiting the Earth in a stable circular orbit at
a height of 5,220 km above the surface of the Earth.
(a) What is the satellite's acceleration in this orbit?
(b) What is the satellite's orbital period?
(c) If the satellite has a mass of 6400 kg, how much work was
needed ti out it in to this orbit, assuming it was initially at
rest? Neglect the Earth's rotation and atmospheric resistance.

A satellite is designed to orbit Earth
at an alltitude above its surface that will place it in a
gravitational field with a strength of 4.5 N/m.
a) Calculate the distance
above the surface of the Earth at which the satellite must
orbit.
b) Assuming the orbit is
circular, calculate the acceleration of the satellite and its
direction.
c) At what speed
must the satellite travel in order to maintain this orbit
