Problem
A vector A has a magnitude of 25m and is directed at an angle of 40∘ above the negative x-axis (that is, in the second quadrant).
(i) Explain the procedure for resolving a vector of known magnitude and direction into its rectangular components.
(ii) Using the method explained in part (i), calculate the x- and y-components of A.
(iii) Write A in unit–vector notation and obtain the unit vector along A.
