(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).

Third Law of Motion and Momentum and Impulse

$A$ spherical body of mass $100 \,g$ is dropped from a height of $10 \,m$ from the ground. After hitting the ground, the body rebounds to a height of $5 \,m$. The impulse of force imparted by the ground to the body is given by: (given $g = 9.8 \,m/s^2$)

$A$ body of mass $m_1$ exerts a force on another body of mass $m_2$. If the magnitude of acceleration of $m_2$ is $a_2$,then the magnitude of the acceleration of $m_1$ is (considering only two bodies in space).
