Two crewmen pull a raft through a lock, as shown in the figure . One crewman pulls with a force of 130 {\rm N} at an angle of 34 ^\circ relative to the forward direction of the raft. The second crewman, on the opposite side of the lock, pulls at an angle of 45 ^\circ .
With what force should the second crewman pull so that the net force of the two crewmen is in the forward direction?
