Question

Determine: initial and final thrust, specific impulse, propellant masses, and useful propellant

Answer 1

The amount of propellant is normally measured either in units of mass or weight. ... Note that the rate of change of momentum of a rocket (including itspropellant) per unit time is equal to thethrust. The higher the specific impulse, the less propellant is needed to produce a given thrust during a given time

Answer 2

Answer:

here is your answer

Explanation:

Specific impulse— Isp is a specification commonly given to engines which produce a thrust force. Jet engines and rocket engines are two common examples.

specific impulse is a measure of the efficiency of using fuel to produce thrust and is one of the most important specifications of such an engine.

I sp = F⋅Δt/m fuel g

i only knew the answer of specific impulse so I did my best to tell the answer.Hope it helps you​
