Hello friend
Good morning
Your answer is given below
=> given that,
Initial velocity, u = 60 km / h
Final velocity = 45 km / h
Time = 10 s
Find retardation
We know 1st equation of motion
=> v = u + at
=> 40 = 45 - a × 10
=> - 5 = - 10 a
=> a = 2 m/s^2
So the retardation = 2m/s^2
I hope it will help you
