I couldn't really see the collision easily, maybe you could add another frame? The ball moves pretty fast, and he kinda stops abruptly when he touches the ground. Other than that, and the ant-size of the stick, its alright.

Use www.filebox.me, www.truploader.com or www.swfcabin.com to host your flash animations, instead of youtube. The quality is too low to give c&c.

The quality isn't that great. But it still doesn't look terrible. The physics are good, except for the ball at the end. it comes to too much of an abrupt stop.
Other than that though it's good.
