1. Rocket Propulsion system. M + Am P = (M + Am)v a Am M (a) The initial mass of the rocket plus all its fuel is M + Am at a time t, and its speed is . (b) At a time i + At, the rocket's mass has been reduced to M and an amount of fuel Am has been ejected. The rocket's speed increases by an amount Av. v + Ay нь A rocket moving in space, far from all other objects, has a speed of 3*10m/s relative to the Earth. Its engines are turned on, and fuel is ejected in a direction opposite the rocket's motion at a speed of 5*10 m/s relative to the rocket. Find: (A) What is the speed of the rocket relative to the Earth once the rocket's mass is reduced to half its mass before ignition? (B) What is the thrust on the rocket if it burns fuel at the rate of 50 kg/s?
