1hey asish,
then have u wondered while deriving expression for escape velocity from earths surface wat u do?????
do u think u take rotation of earth into account........... [1]

106if the earth was not rotating then answer wud have been a,b,c,d .. As earth is rotating , if u project along some latitude or direction then the rotational vel. will be superimposed (added) with the velocity u r projecting..
So a,b only

9ashish is right
we dont take rotation into acc while deriving escape vel cos the diff is very small
1hey wat u r telling is ironical to me...........
u r saying that we don take into account as difference is very small..........
we don take it into account becoz we can't conserve enrgy in a non-inertial frame,so,we neglect the angular velocity and treat it as a inertial frame....................
so,the escape velocity is independent of latitude and direction of projection
9"escape vel is independent of latitude , direction "
means velocity of rocket is same
but here it is launched by a meachanism
so relative velocity comes into play
analyse carefully ull get it
