A mass m orbits around a planet of mass m in a parabolic, Ask an Expert

Academics

A mass m orbits around a planet of mass M in a parabolic orbit of the form y = x^2/(4L), which has focal length L. Find the angular momentum in 3 different ways:

a) Find the speed at closet approach.

b) Use k = (L^2)/(mα)

c) Consider the point (x, (x^2/4L)), where x is very large. Find approximate expressions for the speed and impact parameter at this point.
