Question

A train is travelling at a speed
of 90 km h . Brakes are applied
so as to produce a uniform
acceleration of - 0.5 m/s². Find
how far the train will go before it
is brought to rest.​

Answer 1

Answer:

U=90kmh=25m/s

v=0

v

${v {}^{2} - {u }^{2} } =2as$

${25 {}^{2} - 0}^{2} = 2( - 0.5)s$

s=625m

distance = 625m
