Question

a bus decreases its speed from 80km h-1 in 5 s find the acceleration of the bus

Answer 1

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

Hope it helps u...

Answer 2

acceleration is equal to -1.1 m per sec^2
