F(A)x =F(A) •cos20°
F(A)y= F(A) •sin20°
F(B)x =F(B) •cos80°
F(B)y= F(B) •sin60°
-------
Fx=F(A)x+F(B)x = F(A) •cos20°+F(B) •cos80° = 85 •cos20°+125 •cos80°=…
Fy=F(A)y+F(B)y = F(A) •sin20°+F(B) •sin80°=85 •sin20°+125 •sin80°=...
F=sqrt(Fx²+Fy²) =...
Mathematically determine the resultant force if two forces A and B act on an object. Force A is 85N and is at an angle of 20• to the horizontal. Force B is 125N and is at an angle of 60• to the horizontal.
