As we know, to break a coconut we have to apply 400 pounds of pressure to it. In pounds = 400psi In newton = 1779.29N Starting from the first person he will try to break the coconut with his hands. As we know humans can exert a force 292 newtons by their hands. So force by hand is approximately = 300 N Then the second and third one also try to break it by hand but they fail too.
