Using the graphical method, find the resultant of the following two displacements: 2.0 m at 40° and 4.0 m at 127°, the angles being taken relative to the +x-axis, as is customary. Give your answer to two significant figures. (See Appendix A on significant figures.) Choose x- and y-axes as seen in Fig. 1-9 and lay out the displacements to scale, tip to tail from the origin. Notice that all angles are measured from the +x-axis. The resultant vector s points from starting point to end point as shown. We measure its length on the scale diagram to find its magnitude, 4.6 m. Using a protractor, we measure its angle 0 to be 101°. The resultant displacement is therefore 4.6 m at 101°.

Transcribed Image Text:Using the graphical method, find the resultant of the following two displacements: 2.0 m at 40° and
4.0 m at 127°, the angles being taken relative to the +x-axis, as is customary. Give your answer to
two significant figures. (See Appendix A on significant figures.)
Choose x- and y-axes as seen in Fig. 1-9 and lay out the displacements to scale, tip to tail from the origin.
Notice that all angles are measured from the +x-axis. The resultant vector s points from starting point to end
point as shown. We measure its length on the scale diagram to find its magnitude, 4.6 m. Using a protractor,
we measure its angle 0 to be 101°. The resultant displacement is therefore 4.6 m at 101°.
