Question

A bus decreases its speed from 30m/s to 20m/s in 5 s. Find the acceleration of the bus.​

Answer 1

⚘ Given That :

• ↣ Initial Velocity of Bus (u) = 30m/s
• ↣ Final Velocity of Bus (v) = 20m/s
• ↣ Time taken by Bus (T) = 5sec

⚘ Need to Find :

• ‣ Acceleration of the Bus ?

⌬ Formula Used Here :

• ✪ a = v - u / t ✪

_______________________

✠ Where :

• ↠ a = Acceleration
• ↠ v = Final Velocity
• ↠ u = Initial Velocity
• ↠ t = Time Taken

★ Putting Values in Formula :

• ➻ a = v - u / t
• ➻ a = 20 - 30 / 5s
• ➻ a = - 10 / 5
• ➻ Acceleration = - 2 m/s²

✧ Therefore :

» ❝ The Acceleration of Bus is - 2m/s² ❞
