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 with sides of length d at a height h 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 of +Q/4 and the satellite with a charge -Q. When the satellite is released from rest, it moves up and passes through the center of the square. At the instant it reaches the square's center, the power supply is turned off and the electrodes are grounded, giving them a zero electric charge. To test this idea, you decide to use energy considerations to calculate how big Q will have to be to get a 100 kg satellite to a sufficient orbit height. Assume that the satellite starts from 15 meters below the square of electrodes and that the sides of the square are each 5 meters. In your physics text you find the mass of the Earth to be 6.0 x 1024 kg and its average radius is 6370 km

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...

The VASIMR Rocket NASA plans to use a new type of rocket, a Variable Specific Impulse Magnetoplasma Rocket (VASIMR ), on future missions. If a VASIMR can produce 6.0 N of thrust (force), and has a mass of 620 kg, (a) what acceleration will it experience? Assume that the only force acting on the rocket is its own thrust, and that the mass of the rocket is constant. (b) Over what distance must the rocket accelerate from rest to achieve...

A rocket carrying a new 990-kg satellite into orbit misfires and places the satellite in an orbit with an altitude of 120 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 545 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...

Jon, 20, is about to begin his career as a rocket scientist for a NASA contractor. Having recently read an article on Social Security in the Wall Street Journal he is concerned that the Social Security Trust Fund will be exhausted by 2032 and decides he should not rely on Social Security to fund his retirement. His retirement plan pays 9 percent annual interest and allows him to make equal yearly contributions. Jon plans to retire at the age of...

NASA has sent satellites to the planet Mars. The method is to put the satellite into a Keplerian orbit whose perihelion is at the position of the Earth and whose aphelion is at the position of Mars. The satellite does not travel to Mars under rocket power; it just moves under the influence of the Sun's gravity. Calculate the number of days the trip to Mars will take.

NASA has launched a mission to a newly discovered object, spherical in shape. A satellite is given a gravitationally driven circular orbit around the object. The altitude of the satellite in its orbit is equal to the radius of the object, and it takes 19.4 × 103 ??? for the satellite to complete one orbit. At the same time, a rover lands on the surface of the object. NASA engineers notice one of the support arms on it is broken...

A new processing facility is being designed by an engineering project team. Your boss has asked you to design a catalytic system that requires pumping a hydrocarbon slurry that is corrosive and contains abrasive particles. You have narrowed your selection of pumps to two different models. Each pump will satisfy the needs of the project and they both have the same output capacity. The accompanying table lists the costs and other financial data for the two pumps. Complete an Annual...

Your job with NASA is to monitor satellite orbits. One day, during a routine survey, you find that a 400 kg satellite in a 1000-km-high circular orbit is going to collide with a smaller 100 kg satellite traveling in the same orbit but in the opposite direction. Knowing the construction of the two satellites, you expect they will become enmeshed into a single piece of space debris. When you notify your boss of this impending collision, he asks you to...

You and a team of scientists are interested in understanding whether your weight gain drug was useful to help underweight population to gain weight. For your sample of 25 people, their weight was measured before, and then post the drug administration. The difference in their weight, was measured and calculated by POST – PRE. The sample had an average difference of + 0.8 lbs, with a standard deviation of 1.5 lbs. Does your sample suggest that your weight gain drug...

You are approaching the end of your time supporting Sifers-Grayson. Your team leader has asked you to prepare a 2 page research and analysis brief ("briefing paper") for the company's executives in which you identify the five most important technologies which the company should adopt in order to improve its security posture. Provide specific details as to why each technology is required (what is the vulnerability or weakness that the technology will address). Then, make a recommendation for how the...
