###### Answer: It is equal to the momentum of object 1 plus the momentum of object 2.

The coefficient of restitution (COR) also denoted by (e) is the ratio of the final to initial relative velocity between two objects after they collide .It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. A perfectly inelastic collision has a coefficient of 0 but a 0 value does not have to be perfectly inelastic.

Thu Oct 21 2004 14:30:00 GMT-0400 (Eastern Daylight Time) · The conservation of momentum (mass × velocity) and kinetic energy ( 1 / 2 × mass × velocity 2 ) can be used to find the resulting velocities for two colliding perfectly elastic objects . These two equations are used to determine the resulting velocities of the two objects . For the case of two balls constrained to a straight path by the strings …

Tue Feb 04 2003 13:30:00 GMT-0500 (Eastern Standard Time) · Coulomb’s law or Coulomb’s inverse-square law is an experimental law of physics that quantifies the amount of force between two stationary electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. The law was first discovered in 1785 by French physicist Charles-Augustin de Coulomb hence the name.

Gravitational waves perform the same function. Thus for example a binary system loses angular momentum as the two orbiting objects spiral towards each other—the angular momentum is radiated away by gravitational waves. The waves can also carry off linear momentum a possibility that has some interesting implications for astrophysics.

The giant-impact hypothesis sometimes called the Big Splash or the Theia Impact suggests that the Moon formed from the ejecta of a collision between the proto-Earth and a Mars-sized planetesimal approximately 4.5 billion years ago in the Hadean eon (about 20 to 100 million years after the Sol…
