Cumulative plot of the contributions to the total mass in the system by the largest (grey slashed), second largest (solid grey), power-law (black slashed), and sub-resolution (solid black) populations after the aggregate collisions at various velocities. At low velocities, where bouncing occurs, the mass is wholly within the first and second largest fragments, while at intermediate velocities, where sticking occurs, the contribution to the mass is in the largest fragments. At high velocities, the mass contribution from the power-law population becomes significant.
