APFIVE Translational Equilibrium of Forces
A 5.0 kg block on a frictionless horizontal surface is subjected to three horizontal forces: F₁ = 20 N east, F₂ = 15 N north, and F₃ = 25 N at 53° south of west. What additional force, F₄, is required to keep the block in translational equilibrium?
A
35 N at 37° north of east
B
10 N at 37° south of east
C
15 N at 53° north of east
D
7.0 N at 45° north of west
