Answer 1

Dear Student,

$$\begin{gathered} \mathrm{u}=0\mathrm{km}/\mathrm{h} \\ \mathrm{v}=36\mathrm{km}/\mathrm{h} \\ \mathrm{t}=10\mathrm{minutes}=\frac{10}{60}\mathrm{h}=\frac{1}{6}\mathrm{h} \\ \mathrm{we}\mathrm{know}\mathrm{that} \\ \mathrm{v}=\mathrm{u}+\mathrm{at} \\ 36=0+\mathrm{a}\times \frac{1}{6} \\ \mathrm{a}=216\mathrm{km}/{\mathrm{h}}^2 \end{gathered}$$
