Question

ILL MARK BRAINLIEEST PLEASE PLEASE HELP ME!! PLEASE NO FAKE ANSWERS!! A bus decreases its speed from 80km/h to 60km/h is 5 second. Find the acceleration of the bus.( Final answer is =1. 11 m/s ^2)

Answer 1

v=u+at
Final speed= 60km/h = 60×5/18
Initial speed= 80km/h = 80×5/18

300/18= 400/18+ a × 5
300/18-400/18=5a
100/18= 5a
5.55=5a
a= 1.11 m/s^2

Answer 2

Hey dear, here is ur answer :
___________________
Given that,
Initial Speed(u) = 80 km/h
= 80×5÷18
= solve it (ans 22.22m/s)
Final Speed(v) = 60 km/h
= 60×5÷18
= solve it (ans 16.66m/s)
Time taken (t)= 5 sec
We know That,
Acceleration = Final Speed- Initial Speed ÷ time taken
=16.66-22.22÷5
= solve it (ans 1.11 m/s square)

I have not solve the answers because u should try this.
Hope this will help u. Thanks.
