Question

A satellite is orbiting the Earth at a distance of 3.27 RE and with a speed of 4.55 km/s. With what speed would the satellite hit the Earth's surface if somehow it suddenly stopped and fell to Earth? Ignore air resistance.

Answer #1

A satellite is orbiting the Earth at a distance of 3.61
RE and with a speed of 4.65 km/s. With what
speed would the satellite hit the Earth's surface if somehow it
suddenly stopped and fell to Earth? Ignore air resistance.

A satellite (mass 2400 kg) is orbiting the Earth, with a speed
of 7500 m/s. What is the height of this satellite above the Earth's
surface?
Note: you may find the following information useful. The
universal gravitational constant is 6.67x10-11
Nm2/kg2 ; the mass of the Earth is 6.0 x
1024 kg; the radius of the Earth is 6.4 x 103
km.
can you please show work if you can? I APPRECIATE YOU!!!

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 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 of mass 190 kg is placed into Earth orbit at a
height of 750 km above the surface.
(a) Assuming a circular orbit, how long does the satellite take
to complete one orbit?
(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.

height of 850 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.

height of 500 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. J

A satellite of mass 180 kg is placed into Earth orbit at a
height of 350 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. J

A space station is orbiting the Earth. It moves in a circular
orbit with a radius equal to twice the Earth's radius. A supply
satellite is designed to travel to the station and dock smoothly
when it arrives. If the supply satellite is fired as a simple
projectile from the Earth's surface, what is the minimum initial
speed required for it to reach the space station and have a speed
equal to the station's speed when it arrives? Ignore both...

A satellite of mass 210 kg is placed into Earth orbit at a
height of 450 km above the surface.
(a) Assuming a circular orbit, how long does the satellite take
to complete one orbit?
1.56 h
(b) What is the satellite's speed?
7647.53 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.
