Any vector can be written as components along positive X and positive Y axes.
So vector A can be written as [tex]Acos(\theta)i+Asin(\theta)j[/tex], where [tex]\theta[/tex] is the angle between vector A and positive X axis
So vector A = [tex]70*cos(51.7)i+70*sin(51.7)j=43.38i+54.93j[/tex]
So components of vector B along X -axis =43.38 m/s
along Y-axis = 54.93 m/s
