Answer:
Here we have, Initial velocity (u) = 0
Acceleration (a) = 0.1ms-2
Time (t) = 2 minute = 120 second
(a) The speed acquired:
We know that, v = u + at
⇒
v
=
0
+
0.1
m
/

120
s
⇒
v
=

m
/
s
Thus, the bus will acquire a speed of 120 m/s after 2 minute with the given acceleration.
(b) The distance travelled:
We know that,
s
=
u

Thus, bus will travel a distance of 7200 m or 7.2 km in the given time of 2 minute.
