Question

In a summer storm, the wind blows with a velocity of 8 m/s north. Suddenly in 3 seconds, the wind's velocity is 23 m/s south. What is the wind's acceleration?​

Answer 1

Initial velocity = 8 m/s

Final velocity = 23 m/s

Time for the velocity change = 3 s

By definition, the average acceleration is

(23 - 8)/3 = 5 m/s²

Answer: 5 m/s²

Hope this helps!! have a great rest of your day!
