what is the final velocity of an object when 1 fall into it?

Question

escape velocity of black hole is>c.when 1 body falls into another body according to law of consevation of energy final velocity is =escape velocity so ur ans may be v>c which is impossible

Answer 1

You misinterpreted something. By your theory, when I jump up from the ground, my final velocity is equal to Earth's escape velocity, which is around 9 meters per second, I think. Probably more. But either way, that is much faster than I can possibly go.

Also, there is NO law which says that velocities higher than c are impossible, it just says that velocities EQUAL to c are impossible.

Answer 2

actually on further thought .. there can be no final velocity for an object entering a black hole... as a black hole swirls down to infinity.. so the concept of a final velocity never occurs...

Answer 3

What would be interesting to know is what are the gravitiational effects at certain radii..form the event horizon or the accretion disc..how close could you get before the G pull would be unescapable...how could we measure it? INITIAL velocity..x the pull of gravity..mayebe?
