Two particles $P$ and $Q$ , of masses $0.1\text{ kg}$ and $0.4\text{ kg}$ respectively, are free to move on a smooth horizontal plane. Particle $P$ is projected with speed $4\text{ m s}^{-1}$ towards $Q$ which is stationary. After $P$ and $Q$ collide, the speeds of $P$ and $Q$ are equal.

Find the two possible values of the speed of $P$ after the collision.
