(D) Given:Initial velocity,$u = 0\, m s^{-1}$Acceleration,$a = 0.1\, m s^{-2}$Time,$t = 2\, min = 120\, s$$(a)$ To find the speed acquired $(v)$:Using the first equation of motion,$v = u + at$$v = 0 + (0.1\, m s^{-2} 	imes 120\, s)$$v = 12\, m s^{-1}$$(b)$ To find the distance travelled $(s)$:Using the second equation of motion,$s = ut + \frac{1}{2}at^2$$s = (0 	imes 120) + \frac{1}{2} 	imes 0.1 	imes (120)^2$$s = 0 + 0.05 	imes 14400$$s = 720\, m$Thus,the speed acquired is $12\, m s^{-1}$ and the distance travelled is $720\, m$.

$A$ bus starting from rest moves with a uniform acceleration of $0.1\, m s^{-2}$ for $2\, min$. Find $(a)$ the speed acquired,$(b)$ the distance travelled.
