A machine gun of mass 20 kg fires bullets, each of 40 g at the rate of 120 bullets per minute with a speed of $100 m s^{-1}$. The recoil velocity of the gun is:

A body which is initially at rest breaks into 2 pieces of masses $4M$ and $6M$ respectively, together having a total kinetic energy $E$. The piece with mass $4M$, after breaking has a kinetic energy of:

A man weighing 80 kg is standing on a trolley weighing 320 kg. The trolley is resting on frictionless horizontal rails. If the man starts walking on the trolley with a speed of 1 $ms^{-1}$, then after 4 seconds his displacement relative to the ground will be:

Three balls $A$, $B$ and $C$ of equal mass are moving in the same order along the same straight line on a smooth horizontal surface. Initially, ball $A$ moves towards right with a velocity of $6\text{ ms}^{-1}$, ball $B$ moves towards left with a velocity of $4\text{ ms}^{-1}$ and ball $C$ moves towards right with a velocity of $3\text{ ms}^{-1}$. If the coefficient of restitution between any two balls is $0.8$, then the relative velocity of balls $B$ and $C$ after collision is

A thin circular ring of mass $M$ and radius $R$ is rotating about its central axis with a constant angular velocity $\omega$. Two objects, each of mass $m$, are gently attached to the opposite ends of a diameter of the ring. The new angular velocity of the ring is:
