Question

a train is traveling from railway station attains speed of 21km/s ​

Answer 1

Answer:

initial velocity of train = 0

final velocity of train = 21 m/s

time taken = 1minutes = 60 sec

Thus,

acceleration = change In velocity/time

= ( 21-0)/60 = 21/60 = 7/20 m/s²

Answer 2

pura question tho likha karo

ya ha complete question

a train startinpg from railway station attains a speed of 21m/s in one minute find the acceleration.

solution

initial velocity of train =0

final velocity of train=21m/s

time taken=1 minute=60sec

so,

acceleration=change in velocity/time

=(21-0)/60 =21/60 =7/20 m/s²
