Linear Momentum and its Conservation problem 21


Two bodies travelling along the same straight line collide in a perfectly elastic collision. Which statement must be correct?


  • The total momentum is conserved but the total kinetic energy will be reduced.


  • The initial speed of one body will be the same as the final speed of the other body.


  • One of the bodies will be stationary at one instant.


  • The relative speed of approach between the two bodies equals their relative speed of

    separation.
