Theoretical questions 1. A force has a magnitude of 10 N, and it is forming and angle of 30° with an x-axis. Find x- and y-components of this force. 2. Calculate the magnitude and direction of a force if its x- and y-components are specified: Fx = 0.832 N, Fy = - 1.455 N. 3. In 2D Cartesian coordinates, a force F has the following components: Fx = - 5.0 N, Fy = 8.0 N. Find the magnitude and direction of the force. 4. A force of 5.0 N is applied to a point object at 30° with the horizontal. Another force of 10.0 N is applied at 120°. a) Determine the net force (the magnitude and angle). b) What force (magnitude and angle) has to be applied to the same object to restore the equilibrium (to obtain zero net force)?

Problem 8: The diagram shows the two forces with magnitudes F1 and F2 acting on a body. The first force is in the positive x direction, while the second makes an angle θ with the negative x direction, as shown. Part (a) Write an expression for the x component of the net force. ΣFx = F1 - F2 cos(θ) Part (b) Write an expression for the y component of the net force. ΣFy = - F2 sin(θ) Part (c) If the magnitudes are related by F1 = 2.9F2, and θ = 28.1 degrees, then what is the angle ϕ that the acceleration vector makes with the x axis, in degrees?
