During an elastic collision between two bodies, which of the following statements are correct? I. The initial kinetic energy is equal to the final kinetic energy of the system. II. The linear momentum is conserved. III. The kinetic energy during t (the collision time) is not conserved.

Options

  1. AII and III only
  2. BI and III only
  3. CI, II and III
  4. DI and II only

Correct answer

C. I, II and III

Step-by-step solution

I. Final total kinetic energy equals initial II. Linear momentum is always conserved III. During collision kinetic energy gets parthy converted to potential energy All statements are correct
