Two crewmen pull a boat through a lock, as shown in Figure 5-25. One crewman pulls with a force of F1 = 145 N at an angle of θ = 37° relative to the forward direction of the raft. The second crewman, on the opposite side of the lock, pulls at an angle of 45°. With what force F2 should the second crewman pull so that the net force of the two crewmen is in the forward direction?
