QUESTION 17 The International Space Station which presently has mass of about 420,000 kilograms, maintains an orbit with an altitude of between 330 and 435 kilometers (205 and 270 miles respectively) above the Earth surface by means of re-boost maneuvers using the engines of the Zvezda module or visiting spacecraft to compensate for 2 km/month orbital decay due to the atmospheric drag. Calculate the following for the low orbit of the ISS (330 kilometers above the Earth surface), assuming that...

1. Ceres is the largest asteroid. Its mean radius is 476 km and its mass is 9.4×10^20 kg. Using this, and G=6.67×10^−11 Nm^ 2 kg^−2, and approximating it as a sphere, compute the speed required to escape the gravity on the surface of Ceres. Speed= ___ m.s^−1. (to two significant figures, don't use scientific notation) 2. 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...

Since Moon is attracted to Earth, why doesn't it fall onto Earth? because it has large tangential velocity because there is another equal force on the Moon that balances gravity because centrifugal force balances gravity because centrifugal force more than balances gravity because it has too much inertia to fall towards Earth A. Ocean tides occur mainly because water always runs to the low spot water always runs to the side of the Earth away from the Moon B. water...

Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...
An object of mass m moves at a constant speed v in a circular path of radius r.
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...

Newton's Thought Experiment In the seventeenth century, Sir Isaac Newton was studying the nature of motion and gravity. He formulated a thought experiment that would eventually become the basis of the development of satellites. Imagine an object is fired from a cannon horizontal to the plane of the earth. The projectile will travel in a horizontal direction and undergo projectile motion as gravity begins to pull the projectile downward However, the earth is a sphere, which means as the projectile...

2. (1) A pendulum clock makes use of the fact that the period of a pendulum is consistent and can be predicted relatively easy. What should the length of a pendulum be if the desired frequency of oscillation is. 3. (1) Near the shore, Tsunamis travel at a speed of 30 mph and the distance between crests is about 6.5 miles. What is the frequency of such a wave? Give your answer in units of Hz. When one crest hits...

An object of mass m 5 kilograms falls vertically to the ground under the action of the earth gravitational acceleration of magnitude g 10 meters per second squared. Denote by y vertical coordinate, positive upwards, and let y 0 be at the earth surface. Recall that the force on the object in this situation is f--mg, where the negative sign says the force points downwards. (a) Write the differential equation satisfied by this system. y"-10 Note: Write t for t,...
