Question

3 A helicopters speed increases from 25 m/s to 60 ms in 5 seconds. What is the acceleration of thishelicopter?

Answer 1

Given data

*The initial speed of the helicopter is u = 25 m/s

*The final speed of the helicopter is v = 60 m/s

*The given time is t = 5 s

The formula for the acceleration of the helicopter is given as

$a=\frac{v-u}{t}$

Substitute the values in the above expression as

$\begin{gathered} a=\frac{60-25}{5} \\ =7m/s^2 \end{gathered}$
