Dragging objects - rotating and easing


I have two drag-related questions.

The first one is how to rotate an object by clicking and holding on it, then moving the mouse round in circles. Think of a clock face, and the user clicking and holding on one of the hands, then spinning it around. The centre point would be the part of the hand that’s attached to the middle of the clock face, and the other end of the hand would be able to rotate 360 degrees around the face.

The second one (and not related to the first one, a separate query altogether) is how to drag something horizontally along the screen, but have it stuck at a certain speed. So if the user tries to quickly drag the clip from left to right, it will not reach the right instantly, but instead follow the cursor at a slow speed.

I hope I have explained my questions well enough.
Thanks for any help in advance.
