Question

A car moving with a velocity of 36 kilometre per hour is brought to rest in 5 seconds calculate its deceleration​

Answer 1

Answer:

initial velocity of car=36km/hr=3.6m/s

final velocity=0m/s

time=5s

Acceleration=   v-u/t

                      0-3.6/5

         - 0.72m/s square

acceleration is negative so it is deceleration
