Question

a bus starting from rest moves with a uniform acceleration of 0.1 metre per second for 2 minutes find to the speed of acquired the distance travelled​

Answer 1

Answer:-

Explanation:-

⭕ Given :-

Initial velocity of a bus, (u) = 0 m/s  

Acceleration gain by a bus,  (a) = 0.1ms–2  

Time taken by the bus (t) = 2 minute = 120 seconds  

⭕ To Find :-

(a) The speed acquired

(b) The distance travelled

⭕ Formula To be used :-

v = u + at   and s = ut + 1/2 at²  

⭕ Solution :-

(a) The speed acquired

We know that, v = u + at  

⇒ v = 0 + 0.1 × 120 m/s  

⇒ v = 12 m/s

Hence, 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/ 2 at2  

= 0 × 120 + 1 /2 × 0.1 × (120)2  

= 1/ 2 × 0.1 ×14400 m

= 720 m  

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

Answer 2

Answer:

Explanation:

Time– 2min=120s

Velocity– 0

Acceleration–0.1ms-²

A.

V=0+0.1ms-²×120s

V=0+0.1ms-²+¹

V=12ms

B.

S=ut+½at2

S=0×120+½×0.1×(120)×2

S=720m
