A train starts from rest and accelerate uniformly at the rate of $5\ m/s^2$ for $5\ sec.$ Calculate the velocity of train in $5\ sec.$

Here, 

Initial velocity of the train $u=0$

Acceleration $a=5\ m/s^2$

Time $t=5\ sec.$

Let $v$ be the final velocity of the train

Using the motion equation, $v=u+at$

Or $v=0+5\times 5$

Or $v=25\ m/s$

Thus, the velocity of the train in $5\ sec.$ is $25\ m/s$.
