Question

The vector A in the XY- plane has a magnitude of A = 3.4 and makes an angle of 131 degrees in the anticlockwise sense with the X- axis. What are the components of vector A in the X and Y directions?

Answer 1

Explanation:

Angle supplement to form a triangle in 2nd Quadrant as angle greater than 90degree in this case= 49degree

Component of Vector A

in X direction [Horizontal Component]=Acos theta =3.4×cos49

in Y direction [Vertical Component]=A sin theta=3.4x sin 49
