Slow

I have a 1984 Mazda Rx7 and it takes off and accelerates really slow, slower than normal i think, what are all the possible problems that could be wrong with it.

Clogged cat? Had a carb'd Prelude that got really slow when the cat got clogged.

Disengage the parking brake.

(sorry. Couldn't help myself)

Seriously, though, there could be any one of a thousand things wrong. Your brakes could be dragging really badly, you could have trashed your motor, you could have a slipping clutch, you could have bad gas (in the fuel tank, not from Taco Bell last night), there might be an elephant hiding in your spare tire well and weighing you down, maybe you're not getting enough gas to the engine, perhaps you don't have good spark, maybe your timing's off. Start with the troubleshooting section of the Hayne's manual titled "Lack of Power" (or something like that).

I had the first cat die one time and destroy everything back from there.... I could barely go up hills :-)

But I'd listen to Rx7carl and check the tune-up stuff first.

(In case you're too lazy to search, this includes things like the fuel filter, plugs, etc. The fuel filter seems to be a common criminal on our cars.)

are the secondaries kicking in? One time a clip or something came off of my carb and the car was a lot slower, but a very easy fix
