The coefficient of restitution for a perfect elastic collision is

Options

  1. A1
  2. B0
  3. C-1

Correct answer

A. 1

Step-by-step solution

We know that, coefficient of restitution, for collision between two objects is e= v ₂- v ₁ u ₁- u ₂ = Relative velocity of separation Relative velocity of approach which gives, e=1 (for elastic collision) e=0 (for perfectly in-elastic collision) 0 < e < 1 (for inelastic collision)
