Question

$\huge\rm\underline\purple{Question:-}$<br />A train starts from rest and accelerate uniformly at the rate of 5 m/s2 for 5 sec. Calculate the velocity of train in 5 sec.​

Answer 1

Given :-

Here, we have

Initial velocity, u = 0 (As train starts from rest)

Acceleration, a = 5 m/s²

Time taken, t = 5 seconds

To Find :-

Final velocity, v = ??

Solution :-

According to the 1st equation of motion,

We know that

v = u + at

So, putting all the values, we get

⇒ v = u + at

⇒ v = 0 + 5 × 5

⇒ v = 5 × 5

⇒ v = 25 m/s

Hence, the final velocity of train is 25 m/s.

And we done......!!
