Two lifeguards pull on ropes attached to a raft. if they pull in the same direction, the raft experiences a net external force of 347 n to the right. if they pull in opposite directions, the raft experiences a net external force of 122 n to the left.
draw a free body diagramfor each situation and find the magnitude of the larger of the two individual forces.

F1 = 234.5

Explanation:

F1 = force applied by the first life guard

F2 = force applied by the second life guard

          F1 + F2 = 347  ...equation 1

             F1 - F2 = 122 ....equation 2

        (347 - F2) - F2 = 122

         347 - 2F2 = 122

           2F2 =347 - 122

            F2 = 225 ÷ 2 = 112.5 N

               F1 + F2 = 347

               F1 + 112.5 = 347

               F1 = 347 - 112.5 = 234.5 N

Therefore F1 = 234.5 and F2 = 112.5

     the larger of the two forces is F1 = 234.5

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.
