Initial velocity,u=80km/h=80×5/18=22.22m/s
Final velocity, v=60km/h=60×5/18=16.66m/s
Time=5 s
Acceleration =v-u/t=16.66-22.22/5=-1.11m/s
Final velocity, v=60km/h=60×5/18=16.66m/s
Time=5 s
Acceleration =v-u/t=16.66-22.22/5=-1.11m/s

Thank you
Thank you
Thank you for your help
Thank you
wrong answer hai
-1.11m/s^2
answer is -10m/s^2
srry
-1.11 is right
i forgot to divide it by 9

howdy !!!
your answer is ----
Given, initial velocity u = 80km/h or 200/9 m/s
& final velocity v = 60km/h or 50/3 m/s
and , time period t = 5s
therefore, a = v-u/t
= 50/3-200/9/5
=> a = -50/5/9 = -1.11m/s^2
hope it help you ★

Initial velocity=80km/h
yes
it convet into m/s
change 80 km/ h in m/s
so in m/s u = 200/9 m/s
Thanks bro
