Question

a bus decreases its velocity from 80 kilometre per hour to 60 kilometre per hour in 5 seconds find the acceleration of the bus​

Answer 1

acceleration = v - u / t

80-60/5

20/5

4

Answer 2

acceleration = final velocity-initial velocity/time

so a= 80-60/5

a=20/5

a=4 m/s^2

that's your answer.
