Question

discuss the conservation of momentum in each of the following case (i) a rocket taking off from the ground (ii) recolling of gun​

Answer 1

Answer:

in 1 st case the ejection of gases is action and propulsion of the rocket upwards is reaction. in 2 nd case bullet leaves gun with a velocity way greater than the velocity acquired by the gun due to recoil since mass of bullet is negligible compared to that of the gun

Explanation:

here we take into account Newton's 3 rd law and conservation of moment tum
