Three questions
1. If the mass of the moon were four times what it is, the distance between the earth and moon would be twice what it is now. Is this a correct statement? Explain why or why not.



2. Describe the imbalance between centripetal force and the gravitational attraction force at different locations on the on the Earth’s surface. How is it created?


3. Where on the Earth’s surface, in relation to the moon’s direction, is the tide-generating force due to the moon equal to zero?

1 A spaceship of mass mo moves in the absence of external forces with a constant velocity vo. To change the motion direction, a jet engine is switched on. It starts ejecting a gas jet with velocity u which is constant relative to the spaceship and directed at right angles to the spaceship motion. The engine is shut down when the mass of the spaceship decreases to m. Through what angle a did the motion direction of the spaceship deviate...

Consider a satellite of mass m in a circular orbit of radius r around the Earth of mass ME and radius RE. 1. What is the gravitational force (magnitude and direction) on the satellite from Earth? 2. If we define g(r) to be the force of gravity on a mass m at a radial distance r from the center of the Earth, divided by the mass m, then evaluate the ratio g(r)/g(RE)to see how g varies with radial distance. If...

QUESTION 1 Part 1 Engineers wish to launch a satellite from the surface of the Moon. What is the minimum speed the satellite must have to escape the Moon’s gravity – that is, what is the escape velocity at the surface of the Moon? The Moon has a mass of 7.3x10^22 kg and a radius of 1.7x10^6 m. a. 1700 m/s b. 5.7x10^6 m/s c. It depends on the mass of the satellite. d. 2400 m/s Part 2 The satellite...

Please make sure to answer all the questions correctly; 1.   In applying the gravity method, we subtract the scalar magnitude of normal gravity (gN) from the magnitude of the total component of the gravitational field (gT) to estimate the magnitude of gravity acceleration in the vertical to the ellipsoid (gz). Expand the error of this assumption using the binomial theorem to show that it is maximum at (gA2/gN), where (gA) is the magnitude of the gravity effect of the anomalous...

2. A ball of negligible size and a given mass is attached to a vertical spring that obeys Hooke's law. At equilibrium, its position and gravitational potential energy is chosen to be "zero". The mass is set in oscillation in a vertical direction. At what point during the oscillation will the ball-earth-spring system have the most negative gravitational potential energy? A. The gravitational potential energy will be the most negative at its lowest position from the earth. B. The gravitational...

1) A Red Car and a Blue Truck are driving down a winding road. Through the first curve in the road, the Red Car is driving twice as fast as the Blue Truck. The second curve is half the radius of the first, which causes the Red Car to slow down to half the speed of the Blue Truck to drive around the curve. Rank the acceleration each vehicle experiences in each curve from largest to smallest. -blue truck in...
