Question

A bus starting from rest attains a velocity of 54 km/h in 60 Seconds. what is its acceleration?

Answer 1

Hola,

Hey user,

Your answer goes like:-

Since bus is starting from rest,

u=0 m/s

v=54 km/hr--> 54×5/18= 15 m/s

t=60 sec

a=?

According to v=u+at ,

v=u+at

a=v-u/t,

a= 54-0 /60,

a= 54/60

a= 0.9 m/s2

Hope this helps!!Plzz mark it as brainliest!!!

Answer:

Since bus is starting from rest,

u=0 m/s

v=54 km/hr--> 54×5/18= 15 m/s

t=60 sec

a=?

According to v=u+at ,

v=u+at

a=v-u/t,

a= 15-0 /60,

a= 15/60

a= 0.25m/s^2

Plz Give me thanks
