Question

In a summer storm the wind is blowing with a velocity of 8m/s north. Suddenly in 3 seconds, the winds velocity is 23m/s north. What is the winds 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
