A Rocket Is Fired Vertically in a Vacuum (Free Space

Question 83

Multiple Choice

A rocket is fired vertically in a vacuum (free space where the gravitational field is negligible) .During the burning process, the exhaust gases are ejected at a constant rate of 1000 kg/s and at a constant velocity with magnitude 400 m/s relative to the rocket.Let M be the total initial mass of the rocket, and assume the rocket starts motion from rest.In order to accelerate to the speed of 800 m/s, the rocket has to burn P % of the total initial mass M as a fuel. Assuming there is sufficient amount of fuel on board, the value of P is equal to:
