A particle of mass

0.20\,\text{kg}

moving along a straight line with speed

5.0\,\text{m}\,\text{s}^{-1}

collides head-on and perfectly elastically with a particle of mass

0.30\,\text{kg}

that is initially at rest on the same line. Calculate the speed and direction of each particle immediately after the collision.
