A giant treasure chest is sitting in the sand, when two rival groups of pirates (the sharks and the squids) come upon it at the same time from opposite directions. Both groups run forward and each pirate grabs a side. On the shark’s side, they have one pirate pulling with 20N, one with 30N, one with 50N, and one with 10N. On the squid’s side, they have one pirate pulling with 10N, one with 25N, one with 30N, and one with 40N.
