Two particles are seen to collide and move jointly together after the collision. During such a collision, for the total system,

Options

  1. Aboth the mechanical energy and the linear momentum are conserved
  2. Blinear momentum is conserved but not the mechanical energy
  3. Cneither the mechanical energy nor the linear momentum is conserved
  4. Dmechanical energy is conserved but not the linear momentum.

Correct answer

B. linear momentum is conserved but not the mechanical energy

Step-by-step solution

This is a case of a totally inelastic collision, in which linear momentum is conserved but the total mechanical energy is not conserved.
