I have a doubt in Conservation of Momentum in this problem…
(Source : Anurag Mishra)
This is a basic problem only. I’m not so strong in Impulse, Conservation of Momentum chapter . So I’m mastering it from the bottom. This is my attempt: Conservation of Momentum is done only in one frame ( inertial ) in both the sides of the equation right? Here the muzzle velocity is referred as the velocity of the Bullet/Rocket with respect to the laucher/barrel… So once the rocket gets out, the velocity of the Man+Launcher changes and shouldn’t (the encircled (in red)) equation be V2=Vo+V1… the whole remaining problem changes with this answer!
Please dont’t mind if its a basic doubt
