3. Vectors

A = (4.0 m)i + (3.0 m)j and B = (−13.0 m)i + (7.0 m)j. You add them together to produce another vector C.
(a) Express this new vector C in unit-vector notation.
(b) What are the magnitude and direction of C?

(II) Let V₁ (→ above V₁) = ― 6.0 î + 8.0 ĵ and V₂ (→ above V₂) = ― 4.5 î ― 5.0 ĵ. Determine the magnitude and direction of

(c) V₁ (→ above V₁) + V₂ (→ above V₂), and
