$\text{v}=3600\text{k}\text{m}/\text{h}\text{r}=\mathrm{1000 }\text{m}/\text{s}$

$\text{p}=\text{m}\text{v}=\left(1\times {10}^{-6}\text{k}\text{g}\right)\left(1000\text{m}/\text{s}\right)={10}^{-\mathrm{3 }}\text{k}\text{g}\text{m}/\text{s}$

Use de broglie's relation.

$\text{λ}=\text{h}/\text{m}\text{v}=\frac{\left(6.626\times {10}^{-34}\text{J}-\text{s}\right)}{\left(1\times {10}^{-\mathrm{3 }}\text{k}\text{g}\right)}$

$=6.626\times {10}^{-\mathrm{31 }}\text{m}$
