Answer 1

Question:-

When a train is traveling at a speed of 60km per hour, the brakes are applied at a speed of 50cm/s². How long after the train stops.

To Find:-

Find time taken to stop.

Solution:-

u = 16.6 , v = 0 , a = 0.5

Now ,

We have to find the time:-

$\longrightarrow\sf \: v = u + at$

$\longrightarrow\sf \: 0 = 16.6 + 0.5t$

$\longrightarrow\sf \: t = \dfrac { 16.6 } { 0.5 }$
