Question

A Train is moving at a velocity of 25 ms. It
is brought to rest by applying brakes which
produce a unipron retardation of a 0.5ms/2 Calcute.
i.) velocity of train after 10s
ii.) mass of train in 20000kg then calcuble the
Force required to stop the train.​

Answer 1

Answer:

1) v=u+at

v=25+(-0.5*10)

v=25-5

v=20 m/s

2(.mass of train =20000kg

then force ,F=m*a

F=20000*0.5

F=10000 N

i hope this will help
