PeroK said:Let's go back to the problem. You found that:

##\cos \theta = \sqrt{\frac{M}{2m}}##

And, I told you something you hopefully already knew, that;

##\cos \theta \le 1##

In order for this scenario to be possible, you must have ##M \le 2m##. If ##M > 2m## it is impossible. With ##M \le 2m## it is possible - that's all we are saying.

Yeah, that´s what I thought :-) Thanks for helping me!
