A force of magnitude 25N acts on a body at an angle of 40∘ above the positive x-axis.
(a) Calculate the horizontal (x) and vertical (y) components of this force.
(b) A second force of magnitude 15N acts vertically downward along the negative y-axis. Resolve this force into its rectangular components.
(c) Using the component method, determine the magnitude and the direction of the resultant of the two forces with respect to the positive x-axis.
