Q. In a snooker game, a player strikes the white ball and imparts a velocity of $4\text{m/s}$. The white ball strikes another red ball which was initially at rest. Assuming that the collision of the balls is perfectly elastic and masses of both balls are the same, what are the velocities of the red and white balls respectively?

Q. If a particle has velocity $v\left(t\right)=4t+2\text{m/s}$, the average speed in $2\text{sec}$ is
