When two bodies collide elastically, then

When two bodies collide elastically, then
  1. kinetic energy of the system along is conserved
  2. only momentum is conserved
  3. both kinetic energy and momentum is conserved
  4. Neither kinetic energy nor momentum is conserved

Solution

In elastic collision, both kinetic energy and momentum are conserved. In this collision, total energy is also conserved.
