Method 1 (Easy)
Optionally, run to both sides and get all of the gold there. When returning, slow down and let the rocket see you. Then, hit the launchpad, and you should just barely pass the rocket. Get the switch and move quickly to the diagonal launchpad, which will take you to the next diagonal launchpad, which will in turn launch you to the exit switch. Get the exit switch and then jump across to the side. Up there, there are two switches, guarded by a rocket. As long as you hold left/right and keep moving, the rocket shouldn't bother you. In fact, the right switch is unnecessary due to the fact that the locked door is right above the exit, but it doesn't hurt to get it anyway, especially if you planning on plummeting to your death at the end.
Drop back down to the level below, and then jump to the exit, letting your body drop into the shaft. Alternatively, use the slope to break your fall, and then jump to the exit.
