Let’s apply the procedural steps of the component method to the addition of the vectors in Figure 3.8a. The vectors with units of meters per second represent velocities.

THINKING IT THROUGH. Follow and learn the steps of the procedure. Basically, the vectors are resolved into components and the respective components are added to get the components of the resultant, which then may be expressed in (unit vector) component form or magnitude-angle form.
