A light particle moving horizontally with a speed 12 m/s strikes a very heavy block moving in the same direction at 10 m/s. The collision is one dimensional and elastic. In elastic collision, the conservation of momentum and conservation of kinetic energy are valid. After the collision, the particle will |

(a) |
move at 12 m/s opposite to its original direction |
(b) |
move at 8 m/s in its original direction |

(c) |
move at 8 m/s opposite to its original direction |
(d) |
move at 12 m/s in its original direction |
