(c) The magnitude of G r is 22 | | (1.59 m) (12.1 m) 12.2 m. rr == + = G (d) The angle between G r and the + x direction is tan –1 [(12.1 m)/(1.59 m)] = 82.5°. 17. It should be mentioned that an efficient way to work this vector addition problem is with the cosine law for general triangles (and since G G ab , and G r form an isosceles triangle, the angles are easy to figure). However, in the interest of reinforcing the usual
