## Answers ( )

Answer:Initial velocity=80km/hr or 22.2m/s

Final velocity=60km/hr or 16.6m/s

acceleration=final velovity-initial velocity/time

16.6-22.2/5

-5.6/5

Acceleration=-1.12m/s²

Retardation=-1.12m/s²

Step-by-step explanation:Hope this helps.

Answer:a= -14,400 km/h

Step-by-step explanation:acceleration=v-u/t

a=60000-80000/5

a= -20000/5

a=-4,000m/s

a= -14,400 km/h

– a=14,400 km/h

negative acceleration is called deceleration

d=14,400 km/h
