2)A satellite moves in an elliptic orbit with e= 0.5 around a planet from which it is launched.When it arrives at an apsis (a radial turning point),its velocity is suddenyl doubled .Show that the new orbit will be either paraboloc or hyperbolic according to which of the turning points the...

a quick question..dun u think. the constant K shud be GMm instead of 2GMm. thanks

thanks thanks a lot for all ur help... ill make sure i apply this concept to the other questions as well.. thanks again!

hi i have this question to do which says.. *)A particle moves in a elliptic orbit under the influence of a central force F= -k/r^2.Prove that the product of the maximim and minimum speeds is equal to [2 pi a/t]^2 where 'a' is the semi major axis of the ellipse and 't' is the period of its...

hi i hv these 2 doubts...i tried using the elliptic equation: r= a(1-e^2)/[1-e cos(theta)] however i can't really figure out how do i determine the answer,,i mean if i could know what exactly to do. 1) the orbit of venus is very near circular (e=0.0068).Assuming that the orbit is completely...

central forces-please chek answer! hello... i have this question in my classical mechanics book and was wondering if some one could help me? the question says that there is a particle of mass "m" that is moving under an attractive central force F=k/r^5 where k<0 show that the particles...

hi there im confused with this question.. Integrate 1) Sin(1/z) dz and 2) Z sin (1/Z^3) where Z is any complex number., over C which is a circle of radius 1 centred at 0 i tried using the cauchy integral formula and stuff but somehow the answer always comes infinity...is...

well obviously yes...thats one way of doing it!

hi there i had my classical mechanics exam today and in that there was a question in which there was a potential energy function V(x) given and we had to find the equilibrium points and the frequency of oscillation near the stable equilibrium point.. the potential energy function was given...

hello evbody.. im studying the chapter on oscillations and harmonic oscillations..including phase spaces etc.etc...our curriculum goes by the book"analytical mechanics" by fowles and cassiday.However iv seen that most of the things that we did in class are not given in the book for which we got...

thanks hey..allday thanks a lot for ur help i finally understood it well...got both the questions..i was initially wondering where did g(x) and f(x) come from when they don't belong to the question..now i know! thanks again!

thanks allday just wonering what do i take as f(x) and g(x) in the second question as stated by you thanks

hi there..i am stuck wid these 2 problems from the subject mathematical methods for physicists and the topic is "linear vector spaces" Q1) If S={|1>,|2>,...|n>} is a basis for a vector space V, show that every set with more than n vectors is linearly dependent? (where |> is a dirac bracket)...

hi there. can neone help with this i am studying Fourier transforms and Fourier integrals at univ.i came across this question which looks pretty simple..however after doing all that boundary value crap..im totallt confused..pLEASE HELP ME! QUESTION is attached in the pic...pleasezz...

hi there i meant the actual reason as to why the 2 masses behave as they do when they are swinging...when the lighter mass hits the heavier one...the heavier goes downwards..however momentarily both are at rest when the lighter mass comes to its mean position...i wanted to know the theoretical...
