Here we have,
Initial velocity (u) = 0 m/s
Acceleration (a) = 0.1ms–2
Time (t) = 2 minute = 120 seconds
(a) The speed acquired:
We know that, v = u + at
⇒ v = 0 + 0.1 × 120 m/s
⇒ v = 12 m/s
Thus, the bus will acquire a speed of 12 m/s after 2 minute with the given acceleration.
(b) The distance travelled:
We know that, s = ut + {1\over2}at^2
= 0 × 120 + {1\over2}× 0.1 × (120)2
= {1\over2}× 0.1 ×14400 m = 720 m
Thus, bus will travel a distance of 720 m in the given time of 2 minute.
(a) Find how far does the car travel in the first 4 seconds. Shade the area on the graph that represents the distance travelled by the car during the period. (b) Which part of the graph represents uniform motion of the car? 
(a) Which of the three is travelling the fastest? (b) Are all three ever at the same point on the road? (c) How far has C travelled when B passes A? (d) How far has B travelled by the time it passes C?
