Given, The bus starts from rest. Hence, the initial speed of the bus = 0\ ms^{-1}

Acceleration of the bus, a = 0.1\ ms^{-2}

Time is taken, t = 2\ min = 2\times60\ s = 120\ s

(a) We know, v = u+at

\\ \implies v = 0+(0.1)(120) = 12\ ms^{-1}

Therefore, the speed acquired by the bus is 12\ ms^{-1}
