Answer: 0.35m/s²
Explanation:The initial value of v is 0 and final value is 21m/s In one minute or 60 seconds so.
Vi =0 m/s
Vf= 21m/s
t = 60 s
a = ( Vf-Vi) / t
= 21-0/60
= 21/60
=0.35m/s²

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
