1. The problem statement, all variables and given/known data I have a question about black holes and energy but have no idea what to do. if someone could just point me in the right direction. the question asks to consider a mass spiraling into a black hole, starting with energy E=0 at infinity. I have to determine E of the object when orbiting the black hole at distance r classically. I'm just stuck right now, not sure what is wrong. 2. Relevant equations what im thinking; T(r)= 1/2 Iw^2 U(r)= -GMm/r there are following questions that I can't get to until i figure this out.
