The Space X rocket, Falcon 9 takes off from Cape Canaveral and the first stage accelerates to 2,833 m/s in 158 seconds. What is the acceleration of the Falcon 9’s first stage?

the kind of relationship between atmospheric  density and altitude is inverse relationship. this means a surge in either will cut the other factor. density is mass per unit volume, it is hard to compute with only altitude 1,291 kilometers given. also, we could also use temperature and pressure to resolve density but they are not delivered.
