Question

bus accelerates uniformly from 54km/h to 72 km/h in s calculate acceleration in m/s^2

Answer 1

hey dude
here is your answer
=============
u=54km/hr
54*5/18=15m/s

v=72km/hr
72*5/18=20m/s

a=(v-u)/t
(20-15)/10
5/10=0.5
=============
hope it will help you.

Answer 2

I am taking the time to be t as it is not mentioned

so, initial velocity = 54 km/ hr =15m/s

final velocity= 72 km/hr = 20m/s

acceleration = (v-u)/t = 5 / t m/s^2


if t= 10 sec, a = 0.5 m/s^2
