Two crewmen pull a boat through a lock, as shown in the figure. One crewman pulls with a force of F1 = 145 N at an angle of θ = 32° 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?

F1*Cos32= F2*Cos45
F2=145*Cos32/Cos45
= 174N
Any value of F2 less than 174N would result in the net force in forward direction.
F2=145*Cos32/Cos45
= 174N
Any value of F2 less than 174N would result in the net force in forward direction.
