Answer:
a = -1.1 m/s2
Explanation:
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.
Hope it helps you Mate
