The total trip consists oF Four straight-line paths. S N W E 108 m 355 m 49 . 0 254 m 344 m 51 . 0 At the end oF the walk, what is the mag- nitude oF the person’s resultant displacement measured From the starting point? Correct answer: 392 . 09 m. Explanation: Let : d 1 = 108 . 0 m , θ 1 = 0 , d 2 = 355 . 0 m , θ 2 = 90 , d 3 = 254 . 0 m , θ 3 = 49 . 0 180 . 0 = 131 , d 4 = 344 . 0 m , and θ 4 = 180 . 0 51 . 0 = 129 . d θ 108 m 131 129 Δ x 1 = (108 m) cos0 = 108 m , Δ y 2 = (355 m) cos( 90 ) = 355 m , Δ x 3 = (254 m) cos( 131 ) = 166 . 639 m , Δ y 3 = (254 m) sin( 131 ) = 191 . 696 m , Δ x 4 = (344 m) cos 129 = 216 . 486 m , and Δ y 4 = (344 m) sin129 = 267 . 338 m .
