Question

A Train Moving with Velocity of 54 Km/h -1 is accelerated so that it's velocity becomes 72 km/h -1 In 15 Seconds Find The Acceleration of train

Answer 1

Hello Friend

Here is your answer

^_^

Given - initial velocity = 54km/hr

= 54×5/18= 15m/s.

Final velocity = 72km/hr

=72×5/18

=20m/s .

Time = 15 seconds.

To find - Acceleration.

Calculation

Acceleration = Final velocity - Initial velocity /time

i.e a=v-u/t

So, a= 20-15/15

=5/15

=1/3

=0.33m/s 2.

Hope it helps
