Rocket final velocity | Problem A rocket with total mass m-is in deep space, traveling with velocity vi in the x-direction. The rocket suddenly shoots some of its fuel out in the y-direction. The mass of the fuel is 1/5 the total mass of the rocket. Which of the following could be the final velocity of the rocket? O V = V; <-1/2,5/4> ما O Ve = V; <1/2, -5/4> O V+ = V; <4/5, -1/2> O V1 = V; <-4/5, 1/2> O V = V; <5/4, -1/2> O V+ = V; <-5/4, 1/2>
