Which is true for rolling friction (µ_r), static friction (µ_s) and kinetic friction (µ_k) ?

• A

  ${\mathrm{\mu }}_{\mathrm{s}}>{\mathrm{\mu }}_{\mathrm{k}}>{\mathrm{\mu }}_{\mathrm{r}}$

• B

  ${\mathrm{\mu }}_{\mathrm{s}}<{\mathrm{\mu }}_{\mathrm{k}}<{\mathrm{\mu }}_{\mathrm{r}}$

• C

  ${\mathrm{\mu }}_{\mathrm{s}}<{\mathrm{\mu }}_{\mathrm{k}}>{\mathrm{\mu }}_{\mathrm{r}}$

• D

  ${\mathrm{\mu }}_{\mathrm{s}}>{\mathrm{\mu }}_{\mathrm{r}}>{\mathrm{\mu }}_{\mathrm{k}}$
