In a rocket of mass 1000 kg

The thrust developed on the rocket is. Force exerted on the rocket is -. This exerts a force on the rocket equal to. The rate of mass of the gas emitted from the rear of a rocket is initially 0. A rocket has a mass of kg. It is supposed that the rocket is outside the gravitational field. The initial upthrust on the rocket when it just starts moving upwards is. A diwali rocket is ejecting 0. The accelerating force on the rocket is. Fuel is consumend at the rate of 50 g per second in a rocket. What is the thrust experienced by the rocket?

.

Now we deal with the case where the mass of an object is changing. We analyze the motion of a rocket, which changes its velocity and hence its momentum by ejecting burned fuel gases, thus causing it to accelerate in the opposite direction of the velocity of the ejected fuel see Figure. If the burn rate of the fuel is constant, and the velocity at which the exhaust is ejected is also constant, what is the change of velocity of the rocket as a result of burning all of its fuel? The problem has the mass and velocity of the rocket changing; also, the total mass of ejected gases is changing. Thus, we can apply conservation of momentum to answer the question Figure. At the same moment that the total instantaneous rocket mass is m i. Thus, the initial momentum of the system is. Therefore, including both the change for the rocket and the change for the exhaust gas, the final momentum of the system is.
