A completely inelastic collision is one in which the two colliding particles
Are separated after collision
Remain together after collision
Split into small fragments flying in all directions
None of the above
A completely inelastic collision is one in which the two colliding particles
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.
