Question

1. a helicopters speed increases from 25 m/s to 60 m/s in 5 seconds. what is the acceleration of this helicopter?

Explanation:

Step1: Recall 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.

Step2: Identify the values of \(v\), \(u\), and \(t\)

Given \(u = 25\space m/s\), \(v=60\space m/s\), and \(t = 5\space s\).

Step3: Substitute the values into the formula
