Two identical balls A and B having velocities of 0 . 5   m   s - 1 and - 0 . 3   m   s - 1 , respectively, collide elastically in one dimension. The velocities of B and A after the collision, respectively, will be

Options

  1. A- 0 . 5   m   s - 1 and 0 . 3   m   s - 1
  2. B0 . 5   m   s - 1 and - 0 . 3   m   s - 1
  3. C- 0 . 3   m   s - 1 and 0 . 5   m   s - 1
  4. D0 . 3   m   s - 1 and 0 . 5   m   s - 1

Correct answer

B. 0 . 5   m   s - 1 and - 0 . 3   m   s - 1

Step-by-step solution

They will exchange their velocities, so, v B = 0 . 5   m   s - 1 and v A = - 0 . 3   m   s - 1 .
