● Physics ●
Initial velocity of train = u = 0 m/s
Final velocity of the train = v = 21 m/s
Time = t = 1 minute = 60 second
Acceleration = a = ?
We know,
a = (v - u)/t
=> a = (21 - 0)/60
=> a = 21/60
=> a = 7/20 = 0.35 m/s²
Initial velocity of train = u = 0 m/s
Final velocity of the train = v = 21 m/s
Time = t = 1 minute = 60 second
Acceleration = a = ?
We know,
a = (v - u)/t
=> a = (21 - 0)/60
=> a = 21/60
=> a = 7/20 = 0.35 m/s²

Mark my answer brainliest
u=0 hoga na plz explain
because the train is starting from rest
that's why u = 0 m/s
oo sorry
where do you live
you are so intelligent

Answer:
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
