Question

a train is traveling at 90kmph when brakes are applied the retardation is 0.5m psecond square find velocity after 10seconds and time taken by train to come to rest

Answer 1

Here,
u=90
v=?
a=. -0.5 (negative acceleration or retardation)
t=10s

so, By applying First equation of motion
that is. v=u+at .
Now , just put these values in the equation and solve further.

Answer 2

hope u got correct answer
