9702Linear momentum and its conservation

Two spheres travel along the same line with velocities u1 and u2. They collide and after collision their velocities are v1 and v2. Which collision is not elastic?

  1. Au1 = 2, u2 = –5, v1 = –5, v2 = –2
  2. Bu1 = 3, u2 = –3, v1 = 0, v2 = 6
  3. Cu1 = 3, u2 = –2, v1 = 1, v2 = 6
  4. Du1 = 5, u2 = 2, v1 = 3, v2 = 6
