Answer:
Explanation:
Acceleration is defined as the rate of change of velocity w.r.t time .
Initial velocity = 80 km /hrs
Final velocity = 60 kh/ hrs
Time = 5sec
a= v-u/t
a=60-80/5
a= -20/5
a= -4m/second *2
-sign denotes here that acceleration is in opposite direction .
Thanku
Hope this helps u

Explanation:
Acceleration = change in velocity/time
80m/hr=80×10^-3km/hr=0.08km/hr
Now, substitute in the formula
60-0.08/5=
11.984
