A bus decreases its speed from 80 km per hour from 60 km per hour in 5 seconds calculate the acceleration of the bus

Answered by admin @ 25/08/2021

U= initial velocity= 80 km/h = 22.2 m/s
v= final velocity = 60 km/h = 16.7 m/s
t= time = 5 s
a= acceleration = ?

a=v-u/t
a= 16.7-22.2/5
a= -5.5/5
Therefore, a=-1.1 m/s^2
