A bus starting from rest moves with a uniform acceleration by $0.1{\text{ms}}^{-2}$  for 2 minutes then the speed acquired and distance travelled

$\text{ a }=0.\text{1 m}/\text{sec}²$

$\text{ t }=\text{ 12}0\text{ sec }=\text{ 2minutes}$

$\text{equation of motion }: \text{ v }=\text{ u }+\text{ a t }$

$=0+0.\text{1}0\text{ × 12}0$

$={\text{ 12 ms}}^{-1}$

$\text{S}=\text{ u t }+\text{ 1}/\text{2 a t}²$

$=0+\text{ 1}/\text{2 ×}0.\text{1}0\text{ × 12}0²$

$\text{S}=\text{ 72}0\text{ meters}$
