6. Consider the two forces, F1 and F2, shown in Figure 5. Assume that these forces are applied on an object in the xy-plane. The first force has a magnitude F1 = 15 N and is applied in a direction that makes an angle ̑ = 30° with the positive x axis, and the second force has a magnitude F2 = 10 N and is applied in a direction that makes an angle β = 30° with the negative x axis. (a) Calculate the scalar components of F1 and F2 along the x and y directions. (b) Express F1 and F2 in terms of their components. (c) Determine an expression for the resultant force vector, FR. (d) Calculate the magnitude of the resultant force vector. (e) Calculate the angle θ that FR makes with the positive y axis.

Determine the magnitude and direction of the resultant force Fr measured counterclockwise from the positive x-axis. Solve (L) by first finding the resultant F' = F2 + F3 and then forming Fr = F' + F1.
