Answer:

Given that

U= initial velocity= 80 km/h = 22.2 m/s

v= final velocity = 60 km/h = 16.7 m/s

t= time = 5 s

Find out

We have to find a= acceleration = ?

Formula

v = u+at

a = v – u/t

a = 16.7 – 22.2/5

= -5.5/5

Therefore, acceleration a = -1.1 m/s2

The negative sign implies that the velocity is decreasing.
