Question

Part A

Which takes more energy per kilogram of satellite: launching the satellite from the ground to a height of 1600 km above the ground or placing the satellite into orbit once it has reached that altitude?

-Both energies are nearly the same. |

- More energy is required to get the satellite up to the appropriate height than is required to put the satellite into orbit once it is already at the appropriate position. |

-More energy is required to put the satellite into orbit once it is already at the appropriate position than is required to get the satellite up to the appropriate height. |

Part B

Repeat previous part for an orbit 3200 km above the ground.

Both energies are nearly the same. |

More energy is required to get the satellite up to the appropriate height than is required to put the satellite into orbit once it is already at the appropriate position. |

More energy is required to put the satellite into orbit once it is already at the appropriate position than is required to get the satellite up to the appropriate height. |

Part C

Repeat previous for an orbit 4800 km above the ground.

More energy is required to put the satellite into orbit once it is already at the appropriate position than is required to get the satellite up to the appropriate height. |

Both energies are nearly the same |

More energy is required to get the satellite up to the appropriate height than is required to put the satellite into orbit once it is already at the appropriate position. |

Answer #1

You wish to put a satellite in orbit around Earth.
Part A
Which takes more energy per kilogram of satellite: launching the
satellite from the ground to a height of 1600 km above the ground
or placing the satellite into orbit once it has reached that
altitude?
-Both energies are nearly the same.

appropriate height than is required to put the satellite into orbit
once it is already...

NASA has asked your team of rocket scientist about the
feasibiltiy of a new satellite launcher that will save rocket fuel.
NASA's idea is basically an electric slingshot that consists of 4
electrodes arranged in a horizontal square with sides of length 5.0
m at a height 15.0 m above the ground. The satellite is then placed
on the ground aligned with the center of the square. A power supply
will provide each of the four electrodes with a charge...

Consider the mechanical energy of a body in geostationary orbit
above the Earth's equator, at rGS=42000 km.
Consider the mechanical energy of the same body on Earth at the
South pole, at re=6400 km. For this problem, we consider the Earth
to be spherical. (Remember, the object at the equator is in orbit,
the object at the Pole is not in orbit.)
G = 6.67×10−11 Nm2kg−2, and the mass of the Earth is M=5.97×1024
kg
What is the difference in...

Problem: Orbital Mechanics
A spaceship is waiting for launch at the Kennedy Space Center
(Located at Latitude 28.52o North of the Equator) . The spaceship
has a mass of m = 2000 kg.
a) What is the gravitational potential energy the spaceship has
sitting and waiting for launch.
b) What is the kinetic energy the spaceship has sitting and
waiting (calculate K relative to the center of the earth).
c) The spaceship is attached to rockets that are going to...

1) A solar collector heats the water in the water tank
of a home. Which energy transformation equation best describes this
situation?

2) In which case is negative work done?
a) The work done by Earth on a ball as the ball, which
was initially at rest, falls 3.0 m down towards Earth.

If we had put the arrow and the lamp really far away in
Part I, what would be the distance between the (5cm converging)
lens and the image? What would the magnification be? What would the
orientation be? (Hint: there's both a mathematical and physical way
to understand this.)
