a helicopters speed increases from 30 m/s to 40 m/s in 5 seconds. what is the acceleration of this…

Explanation:

Step1: Identify the formula for acceleration

The formula for acceleration $a$ is $a=\frac{v - u}{t}$, where $v$ is the final velocity, $u$ is the initial velocity, and $t$ is the time - interval.

Step2: Determine the values of $v$, $u$, and $t$

Given that $u = 30\ m/s$, $v = 40\ m/s$, and $t = 5\ s$.

Step3: Substitute the values into the formula

$a=\frac{40 - 30}{5}=\frac{10}{5}$

Step4: Calculate the acceleration

$a = 2\ m/s^{2}$

Answer:

$2$
