Question

A bus starting from rest attains a velocity of 72km/h in 5 minutes. Find the acceleration.​

Answer 1

Answer:

u=0   ( starting from rest)

v= 72 km/h   72x5/18=20m/s

t= 5min=60x5=300s

a=(v-u)/t

=20/300

2/30

1/15

=0.06m/s^2

Answer 2

Answer:

acceleration = 0.066.. m/s^2

Explanation:

final velocity , v = 72 km/h = 20 m/s

initial velocity , u = 0

time , t = 5 minutes = 300 second

acceleration = (v - u) / t

a = (20 - 0)/300 = 1/15 m/s^2 = 0.066.. m/s^2
