A train is travelling with a velocity of 15m/s. It then accelerates at 0.5 m/s2 for 6 seconds.
Use the formula v=u+ at to calculate the velocity of the train after the 6 seconds.

Given that,

Initial speed, u = 15 m/s

Acceleration, a = 0.5 m/s²

Time, t = 6 s

To find,

Velocity after 6 seconds.

Solution,

Let v is the velocity of the train.

Using equation : v = u +at

Put all the values,

v = 15 +0.5(6)

= 15 + 3

= 18 m/s

So, its final velocity is 18 m/s.
