Find r/a and wt for twenty values of E between 0 and 47, for some value of e between 0 and 1 of your choice. Graph these pairs: r/a on the vertical axis and wt on the horizontal axis. They form a curve which is a trochoid. Graph the same parametric function for e → 1. This curve is a cycloid.

Hi, I need the last question answered only. Thank you. Please show work
The energy of the particle from Problem 2 is given by
1
E =
M2
+U =
(2)
2mr2
2a
Show that the motion of the particle r(t) is given by parametric equations:
1
t =
- -esin ξ),
r = a(1 – e cos E),
(3)
where w =
[a/(ma³)]/2 is the mean angular velocity of the orbital motion and & is a parameter
(which ranges from 0 to 27 for one revolution). The first relation, which gives (t), is called the
Kepler equation. Substituting r(t) into the equation of path (1) gives o(t).
Hint: Use equations (3) to calculate
dr/dE
and then substitute r and r into equation (2).
