NASA has asked your team of rocket scientists about the feasibility 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 5 m on a side. The satellite is placed 15 m directly under the center of the square. A power supply will provide each of the four electrodes with the same charge and the satellite with an opposite charge 4 times larger....
please answer these and please make it clear for my
understanding
thank you very much in advance
1. Explain how momentum is the key to rocket succes 2. To put a one tonne satellite in to low earth orbit requires a delta v of around 10 km per second from the launch pad. Explain what this means and why a velocity of this magnitude is required. 3. How much kinetic energy will this satellite have in orbit? Compare that with...
A satellite in Earth orbit has a mass of 99 kg and is at an altitude of 1.98 X 100 m. (Assume that U = 0 asr →0.) (a) What is the potential energy of the satellite-Earth system? What is the equation for gravitational potential energy when the altitude is comparable to the radius of the Earth? ) (b) What is the magnitude of the gravitational force exerted by the Earth on the satellite? (c) What force, if any, does...
A rocket carrying a new 945-kg satellite into orbit misfires and places the satellite in an orbit with an altitude of 175 km, well below its operational altitude in low-Earth orbit. (a) What would be the height of the satellite's orbit if its total energy were 450 MJ greater? km (b) What would be the difference in the system's kinetic energy? (Include the sign of the value in your answer.) Mj (c) What would be the difference in the system's...
The region around the Earth is filling up with space junk such as old satellites. One idea for cleaning up space involves using sails that create drag (see figure below) Perhaps one day satellites will be equipped with sails that are deployed at the end of their missions. The NASA mission NanoSail-D was launched in 2010 to test this idea. This problem compares the drag on a solar sail due to the Earth's upper atmosphere with the force exerted on...
All questions please
101. The mass of the Earth is almost 6.0x104 kg, and the average radius is about 6400 km. A satellite with a mass of 70 Kg is orbiting at an altitude of 600 km.

The mass of the Earth is almost 6.0x 10* kg, and the average radius is about 6400...
4. Use Kepler's Second Law and the fact that L-fxp to determine at which points in an elliptical orbit around the Sun a planet has maximum and minimum speeds. (Section 13.5 will help.) 5. At the end of example 13.10, there's an "Evaluate" blurb about how inside the surface of the Earth the force of gravity varies proportionally to the distance from the center, and it makes reference to the next chapter. which is about oscillation. Model the motion of...
