Chapter 3, Problem 35P

Vector $\stackrel{\to }{A}$ has a negative x component 3.00 units in length and a positive y component 2.00 units in length. (a) Determine an expression for $\stackrel{\to }{A}$ in unit-vector notation. (b) Determine the magnitude and direction of $\stackrel{\to }{A}$. (c) What vector $\stackrel{\to }{B}$ when added to $\stackrel{\to }{A}$ gives a resultant vector with no x component and a negative y component 4.00 units in length?
