Question

Please send me solution as soon as possible ​

Answer 1

Explanation:

a=0.5m/s

u=90km/h=(90*5/18)m/s=25m/s

v=0(The train is brought to rest)

so, as we know,

v^2=u^2+2as(third equation of motion)

or, 0^2=25^2 - 2*0.5.s(as the body retards,u>v)

or, s=625m(answer)

The train will go 625m before it comes to rest.
