Question

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

Answer 1

Answer:

5m/s²

Explanation:

Given u = 8m/s

v = 23m/s , t = 3sec .

We know that. :

v = u + at

23 = 8 +a*3

15 = a*3

a = 5m/s²Answer ..

Hope it's helpful

Answer 2

➭ Given :-

➝ Initial Velocity, u = 8m/s

➝ Final Velocity, v = 23m/s

➝ Time, t = 3sec

➭ To find :-

➝ the wind’s acceleration

➭ Solutíon :-

we know..

$\longrightarrow \sf v = u + at$

here,

• v = final Velocity
• u = initial Velocity
• a = acceleration
• t = time

$\longrightarrow \sf 23 - 8 = a \times 3$

$\longrightarrow \sf 15 = a \times 3$

$\longrightarrow \sf a = \cancel \frac{15}{3}$

$\longrightarrow \sf a = 5 {ms}^{ - 2}$

Hence, the wind’s acceleration is 5m/s²
