NASA launches a satellite into orbit at a height above the
surface of the Earth equal to the Earth's mean radius. The mass of
the satellite is 830 kg. (Assume the Earth's mass is 5.97 1024 kg

the satellite to go around the Earth once? h (b) What is the
orbital speed, in m/s, of the satellite? m/s (c) How much
gravitational force, in N,...

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) What is the speed of a 231 kg satellite in an approximately
circular orbit 646 km above the surface of Earth?
b) What is the period? min Suppose the satellite loses
mechanical energy at the average rate of 2.0 ✕ 105 J per orbital
revolution. Adopt the reasonable approximation that the trajectory
is a "circle of slowly diminishing radius".
c) Determine the satellite's altitude at the end of its 1700th
revolution. m
d) Determine its speed at this time....

A satellite of mass 180 kg is placed into
Earth orbit at a height of 700 km above the surface.
(a) Assuming a circular orbit, how long does the
satellite take to complete one orbit?
h
(b) What is the satellite's speed?
m/s
(c) Starting from the satellite on the Earth's surface, what is the
minimum energy input necessary to place this satellite in orbit?
Ignore air resistance but include the effect of the planet's daily
rotation.

A particular satellite was placed in a circular orbit about 595
mi above Earth.
(a) Determine the orbital speed of the satellite. in m/s
(b) Determine the time required for one complete revolution. in
