How Do You Calculate the Forces Exerted by Each Lifeguard on a Raft?

[snash1057]

please help with this exerted force question!?

Two lifeguards pull on ropes attached to a raft. If they pull in the same direction, the raft experiences a net external force of 304 N to the right. If they pull in opposite directions, the raft experiences a net external force of 115 N to the left.


Find the force exerted by each lifeguard on the raft. (Disregard any other forces acting on the raft.)
____N( larger force)
____N( smaller force)




i know this has something to do with F1 and F2, but i don't know what to do with them

Try drawing a force diagram for the raft.
