Two crewmen pull a boat through a lock, as shown in the figure below. One crewman pulls with a force of size F1 = 145 N at an angle of = 34° relative to the forward direction of the boat. The second crewman, on the opposite side of the lock, pulls at an angle of 45°. How large a force F2 should the second crewman pull so that the net force of the two crewmen is in the forward direction?
