Question

A bus decreases its speed from 80 km/h to 60 km/h in 5 seconds. find the acceleration of the bus

Answer 1

heya.....

initial velocity = 80km/h = 22.2m/s
final velocity = 60km/h = 16.6m/s
time = 5 s
acceleration = final - initial ÷ time
16.6 - 22.2 ÷ 5

= -1.12 m/s
hope it helps plz mark as brainliest....

Answer 2

☆☆heya your answer is here☆☆

solution:-

give that..

u= 80×5/18= 22.2m/s
v= 60×5/18= 16.66m/s
t= 5s

formula is:- v= u+at
16.66= 22.2+5a
5a= -22.2+16.66
a= -5.56/5
acceleration (a)= -1.11m/s^2

i hope it is help full for u...
