Question

a train starting from railway station at in the speed of 21 m per second in 1 minute find its acceleration. its urgent please try to give answer fast

Answer 1

u = 0 , v = 21m/s , t = 1min = 60s

a = (v - u)/t

= ( 21 - 0)/60

= 21/60 =

$a = 0.35ms {}^{ - 2}$


Thanks

Answer 2

Hi...☺

Here is your answer...✌

GIVEN THAT,

Initial velocity , u = 0 m/s

Final Velocity , v = 21 m/s

And

Time taken , t = 1 min = 60 s

Now,
We know that

Acceleration

$a = \frac{v - u}{t} \\ \\ a = \frac{21 - 0}{60} = \frac{21}{60} \\ \\ a = 0.35 \: m/ {s}^{2}$

HENCE,

Acceleration = 0.35 m/s²
