Answer 1

Given :

Initial speed of the bus = 0 m/s

Acceleration 0.1 m/s²

Time taken, t = 2 minutes = 120 s

To Find :

(a) Speed acquired,

(b) Distance travelled.

Solution :

Putting all the value,

we get (a) Speed acquired,

v=u+at

v=0+ 0 × 1 × 120

v= 12 m/s

(b) Distance travelled = (12)2-(0)2= 2(0.1) s

s = 720 m

Hence, Speed acquired finally by the bus is 12 m/s. And Distance travelled by the bus is 720m.

Answer 2

Answer:

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. Thus, the bus will acquire a speed of 120 m/s after 2 minute with the given acceleration. Thus, bus will travel a distance of 720 m in the given time of 2 minute.

Explanation:

a=0.1m/s2

and t=2min=120s

(A)v=u+at=0+0.1×120

⟹v=12m/s

(b)s=ut+ 1 at²

2

⟹s=0+ 1 ×0.1×(120)²

2

⟹s=720m
