Question

a bus decrease it's speed from 80 km h-1 to 60 km h-1 in 5 second. Find the acceleration of the bus

Answer 1

u=80 km/h=22.22 m/s

v=60 km/h=16.66 m/s

Time=5 s

Acceleration=(v-u)/t

=(16.66-22.22)/5

=-1.11m/s^2

Answer 2

Hey your answer is here

u = 80 km/h

v = 60 km/h

t = 5 s

a = v - u/t

a = 60 - 80 / 5

a = - 20/5

a = - 4km/h^2

a = 4 x 5/18 m/s

a= 1.11 m/s^2
