Chapter 1, Problem 42P

Vector $\stackrel{\to }{A}$ has components A_x = 1 30 cm, A_y = 2.25 cm: vector $\stackrel{\to }{B}$ has components B_x = 4.10 cm. B_y = −3 75 cm. Find (a) the components of the vector sum $\stackrel{\to }{A}+\stackrel{\to }{B}$; (b) the magnitude and direction of $\stackrel{\to }{A}+\stackrel{\to }{B}$; (c) the components of the vector difference $\stackrel{\to }{B}-\stackrel{\to }{A}$; (d) the magnitude and direction of $\stackrel{\to }{B}-\stackrel{\to }{A}$.
