(a) In unit-vector notation, what is the sum \(\vec{a}+\vec{b}\) if \(\vec{a}=(4.0 \mathrm{m}) \hat{\mathrm{i}}+(3.0 \mathrm{m}) \hat{\mathrm{k}}\) and \(\vec{b}=(-13.0 \mathrm{m}) \hat{\mathrm{i}}+(7.0 \mathrm{m}) \hat{\mathrm{k}}\) ? What are the
(b) magnitude and
(c) direction of \(\vec{a}+\vec{b}\)?
