Question

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

Answer 1

given,
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 train = 0.5 m/s^2
    i hope that this will help u...........................^_^

Answer 2

Acceleration = $\frac{v-u}{t}$

v=30 m/s

t = 1m = 1×60 = 60s

u=0

a = $\frac{30-0}{60}$


                                                                a =0.5 m/s²
