When two bodies collide elastically, then

Options

  1. Akinetic energy of the system along is conserved
  2. Bonly momentum is conserved
  3. Cboth kinetic energy and momentum is conserved
  4. DNeither kinetic energy nor momentum is conserved

Correct answer

C. both kinetic energy and momentum is conserved

Step-by-step solution

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