A spacecraft approaching the planet Saturn reaches point A
Chapter 13, Problem 13.102(choose chapter or problem)
A spacecraft approaching the planet Saturn reaches point A with a velocity \(v_{A}\) of magnitude \(68.8 \times 10^{3} \ \mathrm{ft} / \mathrm{s}\). It is to be placed in an elliptic orbit about Saturn so that it will be able to periodically examine Tethys, one of Saturn’s moons. Tethys is in a circular orbit of radius \(183 \times 10^{3} \ \mathrm{mi}\) about the center of Saturn, traveling at a speed of \(37.2 \times 10^{3} \ \mathrm{ft} / \mathrm{s}\). Determine (a) the decrease in speed required by the spacecraft at A to achieve the desired orbit, (b) the speed of the spacecraft when it reaches the orbit of Tethys at B.

ANSWER:
Problem 13.102A spacecraft approaching the planet Saturn reaches point A with a velocity vA of magnitude68.8 3 103 ft/s. It is to be placed in an elliptic orbit about Saturn so that it will be able toperiodically examine Tethys, one of Saturn's moons. Tethys is in a circular orbit of radius183 3 103 mi about the center of Saturn, traveling at a speed of 37.2 3 103 ft/s. Determine(a) the decrease in speed required by the spacecraft at A to achieve the desired orbit, (b)the speed of the spacecraft when it reaches the orbit of Tethys at B.
