1. A vector a G can be represented in the magnitude-angle notation ( a , θ ), where 22 x y aa a =+ is the magnitude and 1 tan y x a a §· = ¨¸ ©¹ is the angle a G makes with the positive x axis. (a) Given A x = 25.0 m and A y = 40.0 m, ( 25.0 m) (40.0 m) 47.2 m A =− + = (b) Recalling that tan = tan ( + 180°), tan –1 [(40.0 m)/ (– 25.0 m)] = – 58° or 122°.
