Question

explain the process of rocket propulsion in the light of Newton's third law of motion

Answer 1

befor firing the rocket total linearbmomentum of the system is zero beause rocket is in rest when it is fired chemical fuel inside the rocket are burned and hot gases pass through nozzles with great speed according to law of consevation of linear momentu, the total linear momentum after firing must be equal to zero as the hot gases gain linear momentum to the rear on leaving the rocket the rocket acquires equal linear momentum in the upward opposite direction
