Answer 2

Answer:

Question 16: A bus starting from rest moves with a uniform acceleration of 0.1 m s-2 for 2 minutes. Find (a)the speed acquired, (b) the distance travelled.

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+0.1m/s2×120s

⇒v=120m/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=ut+12at2

⇒s=0×120s+12×0.1ms2×(120s)2=12×1440m720

m

Thus, bus will travel a distance of 720 m in the given time of 2 minute.
