Shown are shells at the top of their trajectories with the indicated velocity. All were fired with the same initial angle from the same launch point. At the top of the trajectory, each shell breaks into two pieces of the indicated masses. When the shell pieces hit the ground, rank these in order of distance of their center of mass from the launch point. (ignore air resistance)
