if an aircraft with a coefficient of lift of 0.05322 is traveling at the velocity of 240 kts at sea level, how much lift is required to fly at level unaccelerated flight if the aircraft weighs 800 lbs? (hint: trick question)

We don't give out answers here, we're here to help you understand the subject matter, not to do the question for you. However, the answer really is in the question. If you don't understand try drawing a free body diagram.

BIG HINT: What can you say about the forces acting on an aircraft in straight and level flight (no acceleration)?

what is a free body diagram, LOL!

i do not study physics nor am i close...i need the answer for something i am doing online, can you answer it for me, telling me to work on it wont help since it would be like speaking chinese to someone only fluent in english :)

Again, we don't do the problems for you.

If you don't know what a free body diagram is, I suggest you look at something a little more basic. You can't start in the middle of a book and expect it to make sense.

The answer is quite literally given in the question, since there are only 3 numbers in the question it can't be too hard to narrow them down. You want lift, lift is a force so which of the numbers given in the question has units of force? That's your answer.
