A satellite is in circular orbit around Earth at an altitude of three Earth radii above the surface.  If the satellite uses onboard retro rockets to cut its speed to one half, at what distance from Earth can it establish a new stable circular orbit?  Hint: vorbit =

A helicopter with a mass of 10,000 kg takes off straight up at t=0. The thrust of the engine is defined given as a function of time: FT= 95 0.18t- (kN). Where t is in units of seconds. How fast is it rising and what is its elevation at t=4s?

37. The International Space Station (ISS), mass 419000 kg, orbits Earth at altitude 390 km. However, over the course of several months its altitude will “decay” and decrease by 10 km due to drag with Earth’s atmosphere. Rocket thrusters firing continuously for 2.0 orbits are used to boost the ISS back to the correct orbit. (a) Determine the “delta-v” (change in speed) associated with an increase in altitude of 10 km (assuming circular orbits at each altitude). (b) Determine the amount of thrust necessary for the boost – you can treat the situation like pushing an object up a ramp that is 10 km high and two orbits long (ignore drag).

can you pls also draw a picture/representation of the scenario described? Thanks so much!

I’m stuck on this problem. Please help with all parts especially starting with Newton’s law and sketching the situation. THANK YOU

Please provide handwritten answer

Hey I'm taking an Asvab practice test with my Asvab book and I was wondering if you could help me with this mechanical question.

Determine the angle 0 at which a particle in Jupiter's circular orbit experiences an attraction from Jupiter that is 1.39 times the attraction from the sun. Use Table D/2 of Appendix D as needed. Sun Answer: 0 = Jupiter

M XCM M A binary system is shown by the image above. It consists of two stars of equal mass. These stars revolve in a circular orbit about thgeir center of mass, which is midway between them. If the orbital speed of each star is 2,280 km/s and the orbital period of each is 11.7 days. Find the mass M of each star.
