Question

A bus decrease it's speed from 80 kilometres per hour to 60 kilometres per hour in 5 seconds . Find the acceleration of the bus.​

Answer 1

Answer:

v=u+at

Step-by-step explanation:

Initial speed   u=80 km/h=80×  18/5 =22.22 m/s

Final speed    v=60 km/h=60×  18/5

=16.67 m/s

Using   v=u+at

Or   16.67=22.22+α×5

⟹ a=−1.1 m/s^2
