Two particles with the same mass of 11 kg are involved in a completely inelastic head-on collision. Before the collision both particles have the same speed of 3 m/s. Which statement below describes the velocities of the particles after the collision? One of the particles continues at 3 m/s, and the other reverses direction and moves at 6 m/s. Each particle's speed is still 3 m/s, but each has reversed its direction. There is not enough information to determine the velocities after the collision. One of the particles continues to move at 3 m/s, while the other particle is at rest. Both particles have zero velocity.
