You should have no problem to pull off the three star ranking for the stage. Simply launch towards the big metal block facing you.
Power Activation Point
Activate your jedi power shortly after you hit the blocks. You will push the blocks toward the wind blowers.
First Shot Result
The falling blocks destroy all the platforms and along them the pigs. You may have to try a few shots before all the falling blocks fall into the right place. However, you should have no trouble getting the three star mastery.
