A fisherman has caught a fish on his pole, and to keep the pole steady he has to apply an upward force of F₂ = 280 N Stan angle of 73.5° with respect to the pole. The length of the pole is 3.2m, and he is holding it a distance 0.55m from the end, where is he applying a downward force F₁ .

F₂ = 280 N
Θ = 73.5°
L = 3.2m
d = 0.55m

Part (a) With how much force, F₁ , in Newtons, does he have to push straight downward on the end of his pole from moving? You may assume the pole is massless.
F₁ = ____ N
