Question

A train travelling at \[50\] kmh\[^{-1}\] starts decelerating as it approaches the train station. If the rate of deceleration of the train is \[500\] kmh\[^{-2}\], how long will it take before it comes to a complete stop?

Answer 1

ANSWER:

Explanation:

WE KNOW THAT,

v=u+at

now according to the ques v=0 and u=50km/hr and a=-500km/hr

t=u/a=50/500=1/10hr

now to convert it in minutes multiply 1/10x60=6minute or 360seconds
