Answer:

625

Explanation:

Finally train will be rest so, final velocity,v=0

0=25−0.5t

25=0.5t

t=0.525

t=50 sec

Again, using equation of motion, 

S=ut+21at2

Where, s = distance

v = final velocity

u = initial velocity

a = acceleration

t = time

Put the value into the equation

Where S is distance travelled before stop

s=25×50−21×0.5×(50)2

s=625 m
