Solved: For the displacement vectors a = (3.0 m)i + (4.0
Chapter , Problem 16(choose chapter or problem)
For the displacement vectors \(\vec{a}=(3.0 \ \mathrm{m}) \hat{\mathrm{i}}+(4.0 \ \mathrm{m}) \hat{\mathrm{j}}\) and \(\vec{b}=(5.0 \ \mathrm{m}) \hat{\mathrm{i}}+(-2.0 \ \mathrm{m}) \hat{\mathrm{j}}\), give \(\vec{a}+\vec{b}\) in
(a) unit-vector notation, and as
(b) a magnitude and
(c) an angle (relative to \(\hat{i}\)). Now give \(\vec{b}-\vec{a}\) in
(d) unit-vector notation, and as
(e) a magnitude and
(f) an angle
