initial velocity of train = 0
final velocity of train = 21 m/s
time taken = 1minutes = 60 sec
so,
acceleration = change In velocity/time
= ( 21-0)/60 = 21/60 = 7/20 m/s²
final velocity of train = 21 m/s
time taken = 1minutes = 60 sec
so,
acceleration = change In velocity/time
= ( 21-0)/60 = 21/60 = 7/20 m/s²

As we know,
acceleration = (Final velocity - Initial Velocity)/Time taken
So here,
1 min =60 seconds
Acceleration = (21-0)/60.
= 21/60
=7/20 m/s^2
Hope you understand..
Thank you
