Hey friends! I will definitely mark your answer as BRAINLIEST if you give relevant answer of my question.


Find acceleration if a train accelerates from 36km/h to 54km/h in 10 seconds.​

Answer 1

Answer:

acceleration= v-u/t

Explanation:

v=54 ×1000÷3600=15 m/s; u= 36 ×1000 ÷3600=10m/s ; t=10 s

Answer 2

Answer:

the acceleration of train is 1/2 m/s^2

Explanation:

Acceleration = final velocity -initial velocity/given time

so here :- final velocity is 54 km/h or 15m/s

Initial velocity =36km/h or 10m/s and time is 10 seconds .

so acceleration = 15m - 10m /10 sec

=>1/2 m/s^2

I HOPE THIS HELPS PLEASE MARK ME AS BRAINLIEST.
