A rocket has a mass of 230 Kg (including its fuel). You igniteit, expelling 200 Kg of gas from the bottom of the rocket at aconstant speed of 120 m/s. over 7 seconds. If the rocket isinitially at rest, what would be its final velocity after the fuelis spent? (assume in space, and no gravityconsideration)?
