i have been trying for more than a week,but i cant solve them,so dont tell me that i havent tried !!!!

these are not simple problems :D

bmp files are readible,but i will write down questions right now !!!!

1.if r and r1 are the radii vectors of two points C and C1 in a parabolic orbit and if k is the distance C-C1.prove that the time in the orbit between C and C1 is:

(T0/12pi)[((r+r1+k)/a)^(3/2)-((r+r1-k)/a)^(3/2)]

where T0 is the length of the sidereal year and 'a' is the semi-major axis of the earth's orbit

2.if r and r1 are the radii vectors of two points C and C1 in a elliptic orbit and if k is the distance C-C1.'t' the time required by the planet to move from C to C1 and T the orbital period,prove that:

(2pi*t/T)=H-sin(H)-(H1-sin(H1))

where sin(H/2)=(1/2)((r+r1+k)/a)^(1/2)

sin(H1/2)=(1/2)((r+r1-k)/a)^(1/2)

Maybe you have tried, but you haven't written anything on this thread. You've just asked for someone to solve them for you. The idea of this forum is that you post your working and/or say where you are stuck, then people try to help.

I know it is a pain to write all your working here, but otherwise, I don't know how to help.

The first question is weird because it talks about a parabolic orbit and mentions the Earth's orbit, which is definitely not parabolic.
