Is there a chance this problem can be solved?

Our Physics Dr. drew this diagram on the board and he said find vo without any further explanation! He stated that it is a complicated problem.

I assume that the object will reach point B with some speed.

I have

Ea = mgh + (1/2)mvo^2

Eb = mgH + (1/2)mv^2 - 100 J

I have many unknowns. I am wondering what is the benefit of the angle! And it is not clear how to find H, it is the height from the ground to point B.

Would it make more sense if I assume there is no speed at point B?
