AES is impractical to break.
This is impossible by definition. RAR uses pretty good cryptography, in fact 128-bit AES, which has insofar never been cracked via cryptanalysis or brute-force. You may want to try to find another format of the same archive with no security or one that is trivial to break, since this one will not be breakable.
