Chapter 1.7, Problem 1.7TYU

Two displacement vectors, $\stackrel{\to }{S}$ and $\stackrel{\to }{T}$ have magnitudes S = 3 m and T = 4 m. Which of the following could be the magnitude of the difference vector $\stackrel{\to }{S}-\stackrel{\to }{T}$? (There may be more than one correct answer.) (i) 9 m; (ii) 7 m; (iii) 5 m; (iv) 1 m; (v) 0 m; (vi) −1 m.
