There are three vectors: A,B,C. Vector A is 70.0 units East creating an angle of 28.0 degrees. Vector B is 40.0 units West creating an angle of 56.0 degrees. Vector C is 46.8 units South. Their magnitudes are given in arbitrary units. Determine the sum of the three vectors.
a) Give the resultant in terms of components.
Rx = .....
Ry = .....
(b) What is the magnitude of the resultant?
What is the resultant's angle above the +x axis?
.......°
What is the magnitude of the resultant??? vector Physics help please?
the answer is
Rx= Acosx +Bcosy+Ccosz : where x, y, and z are the angles corresponding to vectors A,B,C(z=90 degrees) and A,B,C is the magnitude of the vectors
Ry=Asinx+Bsiny+Csinz: same x,y, z as above
the magnitude is the square root of Rx^2 +Ry^2
the angle is tan^-1(Ry/Rx)
