A car is standing $\displaystyle 200$ m behind a bus, which is also at rest. The two start moving at the same instant but with different forward accelerations. The bus has acceleration $\displaystyle 2 \mathrm{~m} / \mathrm{s}^2$ and the car has acceleration $\displaystyle 4 \mathrm{~m} / \mathrm{s}^2$. The car will catch up with the bus after a time of :
Official answer
(3)
$\displaystyle 10 \sqrt{2} \mathrm{~s}$
