10. Two lifeguards pull on ropes attached to a raft. If they pulled in the same direction, the raft experiences a net force of 334N
to the right. If they pull in opposite directions, the raft experiences a net force of 105N to the left.
a. Draw a free-body diagram for each situation.
Find the force exerted by each lifeguard on the raft. (disregard any other forces acting on the raft.)
