    Answer:

    1. 60 m/s.

    2. 3600 m.

    Explanation:

    The following data were obtained from the question:

    Initial velocity (u) = 0

    Acceleration (a) = 0.5 m/s²

    Time (t) = 2 mins

    Final Velocity (v) =?

    Distance travelled (s) =?

    1. Determination of the velocity at the end of 2 minutes.

    Initial velocity (u) = 0

    Acceleration (a) = 0.5 m/s²

    Time (t) = 2 mins = 2 x 60 = 120 secs

    Final Velocity (v) =?

    v = u + at

    v = 0 + (0.5 x 120)

    v = 60 m/s

    Therefore, the velocity at the end of 2 minutes is 60 m/s.

    2. Determination of the distance travelled.

    Initial velocity (u) = 0

    Acceleration (a) = 0.5 m/s²

    Final velocity (v) = 60 m/s

    Distance travelled (s) =..?

    v² = u² + 2as

    60² = 0 + 2 x 0.5 x s

    3600 = 1 x s

    s = 3600 m

    Therefore, the distance travelled is 3600 m.
