$A$ body of mass $2 \ kg$ moving with a velocity of $3 \ m/s$ collides head-on with a body of mass $1 \ kg$ moving with a velocity of $4 \ m/s$ in the opposite direction. After the collision,the two bodies stick together and move with a common velocity:

$A$ bullet of mass $m$ moving with velocity $v$ strikes a block of mass $M$ and gets embedded in it. The kinetic energy of the system is:

Discuss the completely inelastic collision in one dimension.

Two masses of $0.25\, kg$ each move towards each other with speeds of $3\, ms^{-1}$ and $1\, ms^{-1}$. They collide and stick together. Find the final velocity in $ms^{-1}$.

Ball $A$ of mass $1 \,kg$ moving along a straight line with a velocity of $4 \,ms^{-1}$ hits another ball $B$ of mass $3 \,kg$ which is at rest. After collision, they stick together and move with the same velocity along the same straight line. If the time of impact of the collision is $0.1 \,s$, then the force exerted on $B$ is (in $\,N$)

$A$ body of mass $10 \, kg$ moving with a speed of $3 \, m/s$ collides with another stationary body of mass $5 \, kg$. As a result,the two bodies stick together. The $KE$ of the composite mass will be .......... $J$.
