An object is moving with a velocity of $5 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$ in a particular direction. Calculate the distance (in $\mathrm{m}$) travelled by it in $5$ seconds.

A minute hand of a clock is $7 \mathrm{cm}$ long. Find the displacement and distance covered by it from $9:00 \mathrm{a}.\mathrm{m}$ to $9:30 \mathrm{a}.\mathrm{m}$.

(Choose one: $3.5 \mathrm{cm}$, $44 \mathrm{cm}$ / $14 \mathrm{cm}, 22 \mathrm{cm}$)
