Question

A train starting from Railway Station attains a speed of21m/s in one minute. Find its acceleration

Answer 1

initial velocity=0
final velocity= 21m/s
time=60 second
acceleration=v-u/t
=21-0/60
=21/60
=0.35m/s²

Answer 2

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
