Question

Determine: Ñ = 3 A + B - 2 C Ż = -A + 2B +30 IV) If Ā = 5.0 cm, due W and B = 3.0 cm, due N Determine: R = A + B Use the polygon method to graph Ā, and i b calculation for the magnitude of Ř and its direct Use the formulas provided in the handout for Ch2 vectors. Examples will be seen in class.

Answer 1

(IV A = som. due West B = 3.0cm_ due North- Ř = ☆ +3 N GW -w. B E IR R 0-7 the angle Between. Å and B a=90. R = J A²+B2+ 2 AB Cosa R = [ (5)² +32 + 2X SA3 (Osgo = √34 Cos90=0 R = 25+9 = 1.84(m.
