Three forces act on a hook attached to the horizontal ground. The hook is at the origin
Question:
Three forces act on a hook attached to the horizontal ground. The hook is at the origin of the x y plane. The x axis points horizontally to the right. The y axis points vertically upward. Force F subscript ?is directed upward and to the left. The angle it makes with the negative x axis is an angle of a right triangle with a hypotenuse of ?a leg adjacent to this angle of ?and an opposite leg of ?Force F subscript ?is directed upward and to the right, making an angle of ?degrees with the positive x axis. Force F subscript ?is directed along the positive x axis.
Determine the magnitude of the resultant force.
Express your answer to three significant figures and include the appropriate units.
