Question

1. in a summer storm, the wind is blowing with a velocity of 8 $\frac{m}{s}$ north. suddenly, the wind accelerates at a rate of 5 $\frac{m}{s^{2}}$ north for 3 seconds. what is the wind’s new velocity? (4 pts)

Explanation:

Step1: Identify the formula

We use the kinematic - equation $v = v_0+at$, where $v$ is the final velocity, $v_0$ is the initial velocity, $a$ is the acceleration, and $t$ is the time.

Step2: Substitute the given values

Given $v_0 = 8\frac{m}{s}$, $a = 5\frac{m}{s^2}$, and $t = 3s$. Substitute into the formula: $v=8 + 5\times3$.

Step3: Calculate the result

First, calculate $5\times3 = 15$. Then, $v=8 + 15$. So, $v = 23\frac{m}{s}$.

Answer:

$23\frac{m}{s}$ north
