Only momentum remains conserved

(A) When the ball hits the sand and embeds itself,it undergoes a perfectly inelastic collision with the sand-earth system.In any collision,the total linear momentum of the system (ball + earth) remains conserved,provided no external impulsive force acts on the system.However,kinetic energy is not conserved in an inelastic collision because a significant portion of the energy is dissipated as heat,sound,and work done against the resistive force of the sand.Therefore,only momentum remains conserved.

Perfectly Inelastic Collision

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 $ms^{-1}$.

$A$ body of mass $1 \ g$ moving with a velocity of $3\hat{i} - 2\hat{j} \ m/s$ collides with a body of mass $2 \ g$ moving with a velocity of $4\hat{j} - 6\hat{k} \ m/s$. If the two bodies stick together after the collision,what is the magnitude of their combined velocity in $m/s$?

$A$ ball moving horizontally with a velocity $2 \,ms^{-1}$ strikes the bob of a seconds pendulum at rest. If the mass of the bob is equal to the mass of the ball and the collision is perfectly elastic, after collision the bob of the pendulum will raise to a height of $(g=10 \,ms^{-2})$ (in $\,cm$)
