Question

a train starting from a railway station attains a velocity of 30 m/s in one minute . what is its acceleration​

Answer 1

Answer:

INITIAL VELOCITY OF TRAIN =0 M/S

FINAL VELOCITY =30 M/S

TIME TAKEN=1 MIN=60 SECONDS

ACCELERATION:

$\frac{v - u}{t} \\ \\ = \frac{30 - 0}{60} = \frac{30}{60} = 0.5m {s}^{ - 2}$

Answer 2

give, initial velocity =0 m/s

final velocity =30 m/s

time taken = 1 min (60 sec)

therefore acceleration,

acceleration = (v-u) /t

acceleration = 30-0/60

acceleration= 30/60

acceleration= 1/2=0.5

therefore acceleration of

the tain =0.5 m/s^2
