Question

a helicopter’s speed increases from 30 m/s to 40 m/s in 5 seconds. what is the acceleration of this helicopter?
□ m/s²

Explanation:

Step1: Identify the formula for acceleration

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

Step2: Substitute the given values into the formula

Here, \(u = 30\space m/s\), \(v=40\space m/s\), and \(t = 5\space s\).

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

Step3: Calculate the value of acceleration

$$a=\frac{10}{5}=2$$

Answer:

\(2\)
