Two crewmen pull a boat through a lock, as shown in the figure below. One crewman pulls with a force of 130 N at an angle of 39o relative to the forward direction of the boat. The second crewman, on the opposite side of the lock, pulls at an angle for 45o. With what force should the second crewman pull so that the net force of the two crewmen is in the forward direction?
