Unformatted text preview: 3.36. CHAPTER 3, PROBLEM 36 255 3.36 Chapter 3, Problem 36 Problem: A space probe is in a circular orbit about Mars, whose radius is R . The radius of the orbit is r i = ξ R , where ξ > 1 is a constant. In order to land on the planet, the probe briefly fires its retrorocket. As a result, the probe’s speed is reduced to ψ v i , where v i is it’s speed before firing the rocket and ψ < 1 is a constant. Assuming the probe moves on the elliptical orbit shown, determine the value of ψ as a function of ξ . v i r i R . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ............................. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
