Ball issue and question

I want to make a game but I have a issue, I want that a ball drops on a rope with collision and then it goes up smooth, I did that with the physics "bounce" it works, but what I want to do is when the rope goes diagonal by hitting a key on your keyboard then it must "bounce" smooth into bucket somewhere in the right top of the screen that when the rope goes diagonal to right, but when it goes diagonal to the left it must go in a other bucket which stands in the left top of the corner.

Can anybody help me it's important.

Thanks in advance.
