Although, this time, I understood what you told me..it just made me more confused. A rocket’s acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket. In part (b), a time Δt has elapsed in which the rocket has ejected a mass Δm of hot gas at a velocity ve relative to the rocket. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. shows a rocket accelerating straight up.
