Vedclass · Answer

(B) Let the velocities of trains $A$ and $B$ be $v_A$ and $v_B$ respectively,where $v_A > v_B$. When a packet of mass $m$ is transferred from $A$ to $B$,it carries a horizontal momentum $m v_A$ to train $B$. Since $v_A > v_B$,the packet imparts an impulsive force on train $B$ in the direction of its motion,causing $B$ to accelerate. Conversely,the packet transferred from $B$ to $A$ carries momentum $m v_B$. Since $v_B Therefore,train $B$ gains momentum (accelerates) and train $A$ loses momentum (retards).

Two trains $A$ and $B$ are running in the same direction on parallel rails such that $A$ is faster than $B$. Packets of equal weight are transferred between them. What will happen due to this?
