Its a slipped belt. Or even a bubble. My car did that only when i broke the stablizer.
When only the back windows are down, they make a thumping sound because of the air tightness of the car's cabin. Roll down a front window slightly and this will go away.
This could be a loose exhaust bracket causing it to hit the underside on acceleration.
it squeaks when you accelerate and stop because that is the wheel (along with the back left) that push the car. i think its correct but im 10 so dont know for sure but i do get straight A's. sorry for bad grammar.
Flat spot on the wheel. Bad wheel bearing. (however its usually the front not the back) Rotate the wheels and see if the problem travels with the a certain wheel
1982 Chevrolet Celebrity with some sinner hubcaps and a 10" sub thumping in the back

WHY DOES MY 95 FORD CROWN VIC WHEN I GO TO ACCELERATE FROM 0-20mph pull back the lurc forward
The A has a short A vowel sound as in bat and pack.
Drop back slightly or accelerate
there boats that have a engine on the back of them that causes the boat to have more speed when they accelerate
It's a short sound. A long sound for a is something like in May.
Rabbits will warn nearby rabbits of danger by thumping their back feet. They will do this when they feel threatened and scared or notice something unusual.
