Question

A train starts from rest and accelerated uniformly at the rate of 5 m/s-2 for 5 sec. Calculate the velocity of train in 5 sec.

Answer 1

Answer:

25 m/s

Explanation:

As train start from rest so its initial velocity will be zero.

now by using the equation, v = u + at

we get the value of final velocity after 5 seconds = 25 m/s

Answer 2

Answer:

Explanation:

Given:

Initial velocity = 0 m/s

Acceleration = 5 m/s²

Time of observation = 5 sec.

To find:

Final velocity after 5 sec.

Concept:

Since the acceleration is constant, we can easily apply equations of Kinematics to get final velocity.

Calculation :

So final velocity = 25 m/s
