Question

A bus increases its speed from 18 km to 54 km/hper hour in 5 sec. Find the acceleration of the bus

Answer 1

a→ acceleration

u→ initial velocity →18km/h = 5m/s

v→ final velocity →54km/h = 15m/s

t→ time taken →5hours=18000second

a = (v-u)/t

a = (15-5)/18000

a = 10/18000

a = 55x10^-5
