Question

A bus starts from rest and picks up a velocity of 90 km/h in 1/2 minute. Calculate the acceleration of the bus in m/s sq.​

Answer 1

GIVEN:-

> Initial velocity = 0m/s

> Final velocity = 90km/h = 25 m/s

> Time = 1/2 min = 30secs

TO FIND:-

>Acceleration

UNDERSTANDING THE CONCEPT:-

According to the question, we know initial velocity, final velocity and time. So by using V = u + at we can find the acceleration.

LET'S DO IT!!

V = u + at

a = v-u / t

$= > \dfrac{25 - 0}{30}$

$= > \dfrac{25}{30}$

$= > 0.8333$

Therefore, the acceleration of the bus = 0.8333m/s^2
