Narrative:
At the beginning of the takeoff roll (well below 80 KTS) crew felt a loud 'thump.' it felt like running over a seam in the concrete. It wasn't an unusual sound. On climbout; the cabin crew called to say they smelled a faint odor of burning rubber in the cabin. The cockpit crew noticed the same odor. The odor dissipated within a few minutes. No other abnormal indications were noted. We began to think we may have blown a tire on takeoff roll. The crew made a call back to the tower to advise and have them inspect the runway. Also called maintenance to advise. We consulted the QRH; which advised continuation to destination. A call back from maintenance confirmed the runway was found to be free of debris. We elected to continue to destination; and encountered no further complications. Upon arrival; maintenance inspection revealed that a cargo pallet in the forward compartment had broken loose and slid aft; damaging an air duct.
