A bus decreases its speed forom 8okmlhto 60kmlh in 5s. Find the acceleration of the bus"Success is about creating benefit for all and enjoying the process.If you focus on this & adopt this definition, success is yours." Kelly, Kim​

Answer»

solution

final VELOCITY =60 km/h (CONVERT it in m/s

by MULTIPLYING by 5/18 =16.66

intial velocity =80km/h (convert in m/s by multiplying by 5/18) =22.22

using formula of acceleration= v-u/t

16.66-22.22/5

-12.21

retardation of 12.21 m/s
