Question

A bus changes its speed from 20 m/s to 60 m/s in 5 s. Find the acceleration of the bus.​

Answer 1

Explanation:

The acceleration of the bus that decreases its speed from 80 kilometers per hour to 60 km per hour in 5 seconds is -1.12m/s.

Answer 2

Answer:

Given:-

Initial Velocity (V ₁) = 20 m/s²

Final Velocity (V₂) = 60 m/s²

Time taken = 5 seconds

Find:- Acceleration of bus

Answer:-

Acceleration =  $\frac{ v2 -v1}{time}$

                     = $\frac{60-20}{5} = \frac{40}{5} = 8 m/s^{2}$

Hope my answer helps you..

Thank you...
