Question

A completely inelastic collision is one in which the two colliding particles-

• A. Are separated after the collision.
• B. Remain together after the collision.
• C. Split into small fragments flying in all directions.
• D. None of the above.

Answer 1

The correct option is B Remain together after the collision.

Completely inelastic collision is one in which the coefficient of restitution is zero.

Coefficient of restitution means the speed of separation of particles is zero.

Thus the two particles remain together after collision.
