Question

What is the sum of the following four vectors in (a) unit-vector notation, and as (b) a magnitude and (c) an angle? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. Upper A Overscript right-arrow EndScripts equals left-parenthesis 2.00 ? m right-parenthesis i Overscript ? EndScripts plus left-parenthesis 3.00 ? m right-parenthesis j Overscript ? EndScripts Upper B Overscript right-arrow EndScripts = 4.00 m, at 65.0° Upper C Overscript right-arrow EndScripts equals left-parenthesis negative 4.00 ? m right-parenthesis i Overscript ? EndScripts minus left-parenthesis 6.00 ? m right-parenthesis j Overscript ? EndScripts Upper D Overscript right-arrow EndScripts = 5.00 m, at -235°
