    Explanation:

    Given that,

    Initial speed of the bus, u = 0

    Acceleration of the bus, a = 0.5 m/s²

    Let v is the velocity at the end of 2 minutes. The change in velocity divided by time equals acceleration.

    So,

    a=\dfrac{v-u}{t}\\\\v=u+at\\\\v=0+0.5\times 120\\\\v=60\ m/s

    Let d is the distance cover during that time. So,

    v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{(60)^2}{2\times 0.5}\\\\d=3600\ m

    So, the final speed is 60 m/s and the distance covered during that time is 3600 m.
