Question

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

Answer 1

Answer:

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

Final speed = v=60 km/h=60×5/18=16.67 m/s

Using v=u+at

Or 16.67=22.22+α×5

⟹ a= −1.1 m/s2

Hope this is helpful for you.

Answer 2

Answer:

1.1 m/s 2

Explanation:

Enter the known values to find unknown

Acceleration

Distance

Final Velocity

Answer

Initial speed u=80 km/h=80×185=22.22 m/s

Final speed v=60 km/h=60×185=16.67 m/s

Using v=u+at

Or 16.67=22.22+α×5

⟹ a=−1.1 m/s2
