1) Find the sum of vectors A + B in cartesian component from using the unit vector X and Y

http://tinypic.com/r/5v6bdy/8 <- is where the graph

2) then find the sum of the vectors in polar form

3) if A+b+c=0 find C?

Note in case the graph isnt showing: In a X and Y planar: Vector A is in the positve quadrant of X and positive of Y, A= 145.0m and the angle= 25.8 Vector B is in the negative quadrant of X and positive of Y, B=45.0m and the angle is 40.6 Thanks a lot

Expert Solution

1) by cartesian co ordinate system

let A = A_xx^ + A_yy^

B = B_xx^ + B_yy^

A + B = (A_x + B_x)x^ + (A_y+B_y)y^

2)

A = 145cos25.8 x^ + 145sin25.8 y^ = 130.5x^ + 63.1y^

B = -45cos40.6 x^ + 45sin40.6 y^ = -34.1x^ + 29.3y^

A + B = 96.4x^ + 92.4y^

3)

C = -(A+B) = - 96.4x^ - 92.4y^
