7. Your spacecraft is in an. initial 200 km altitude circular earth orbit. Performing a Hohmann transfer compute: a) the TOTAL delta-v required for a Hohmann transfer to a 1000 km altitude coplanar circular earth orbit. b) What is the transfer time in minutes?
The new position is r = 6867.3(xhat) + 398.8(yhat). The answer to the first problem would be theta = arctan(398.8/6867.3) = 0.058 degrees. But how do you know how much the line of nodes, which is the new position as show in the diagram, should have rotated for a true sun-synchronoous orbit? What is the formula? What are some reasons why there would be any discrepancy between the estimated angle and the actual angle?

An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 9.791 m/s². Determine the orbitql period of the satellite? Your answer should be a unit of time.
A satellite is in a circular earth orbit of radius min = 1.66R, where R is the radius of the earth. What is the minimum velocity boost Av necessary to reach point B, which is a distance max = 3.94R from the center of the earth? At what point in the original circular orbit should the velocity increment be added? CO Answer: Av = i max m/s

Hello there, Was going through some example questions on my mechanics module and came across this question and have been struggling. The ball has a mass of 3kg, the vertical wall BC is 1000cm high - assume there is no friction. Due to gravity the ball goes down the path AB and then hits the ground at point D. How would I calculate the velocity of the ball at point B, and calculate the time the ball takes to reach point D and the distance CD.
On route to Eris, our experimental payload requires a heliocentric velocity of 25,000 m/s. The mission will employ gravity assist from a flyby of Jupiter. Assuming that the spacecraft propulsion and initial maneuvers have allowed the craft to reach 19,000 m/s relative injection velocity, what approach angle relative to the desired departure trajectory is required? Give your answer as an angle, in degrees.
