Solution Verified by Toppr

Correct option is C)

Given: t=10 min=10×60=600s

Initial speed of train is given as: u=0 ms

−1

Final speed of train is given as: v=40 km h

−1 = 3600 40×1000 ​ =11.1 ms −1

Now acceleration is given by the relation:

a= t v−u ​ = 600 11.1−0 ​ =0.0185 ms −2

Question

A train starting from a railway station and moving with uniform acceleration attains a speed of

40 kmh-1 in 10 minutes

. Find its acceleration in the units of

ms-2 . Open in App Solution

Step 1: Given

Initial speed, u = 0 ms-2 Final velocity,

v = 40 kmh-1 = 40×518=1009ms-1

Time,

t = 10minutes = 600 seconds

Step 2: Formula used and calculation

Using the first equation of motion

v = u +at

⇒1009ms-1 = 0 + 600 s×a

⇒a = 1009×600 ms-2 ⇒a = 0.0185 ms-2

Hence, the acceleration of the train is

0.0185 ms-2 . Suggest Corrections 150 SIMILAR QUESTIONS

## A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km ^(

Here, initial speed (u) = 0 ms ^(-1), t = 10 minute =600s Final velocity (v) = 40 km h ^(-1) =(40 xx 1000)/(3600) = (100)/(9) ms ^(-1) Acceleration = (v0u)/(t)= (( 100)/(9) - 0)/( 600) = (100)/( 9 xx 600) = (1)/( 54) m s^(-1) The acceleration is (1)/(54) ms ^(-2).

Text Solution Open Answer in App Solution Here, initial speed (u)=0m s −1 , (u)=0ms-1, t=10 t=10 minute =600s =600s Final velocity (v)=40km h −1 = 40×1000 3600 = 100 9 m s −1

(v)=40kmh-1=40×10003600=1009ms-1

Acceleration = v0u t = 100 9 −0 600 = 100 9×600 = 1 54 m s −1

=v0ut=1009-0600=1009×600=154ms-1

The acceleration is 1 54 m s −2 . 154ms-2. Answer
