Spacecraft a and b are in the same circular earth orbit with a period of 2 hours. spacecraft b is 6 km ahead of spacecraft a. at t = 0, spacecraft b applies an in-track delta-v (retrofire) of 3 m/s. using a clohessy-wiltshire frame attached to spacecraft a, determine the distance between a and b at 30 minutes and the velocity of b relative to a-

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

i will answer your question if you answer mine

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
