Halliday, Resnick & Walker — Vectors: Problem 33

For the vectors in Fig. 3.12, with \( a = 4, b = 3, \) and \( c = 5 \), what are (a) the magnitude and (b) the direction of \( \vec{a} \times \vec{b} \), (c) the magnitude and (d) the direction of \( \vec{a} \times \vec{c} \), and (e) the magnitude and (f) the direction of \( \vec{b} \times \vec{c} \)? (The \( z \) axis is not shown.)
