The average speed of the airplane is 8.4 m/s

<h3>Further Explanation</h3>

<u>Given :</u>

number of rotation = N = 10

time intervals = Δt  = 30 s

radius = R = 4.0 m

<u>Unknown :</u>

average speed = v = ?

<u>Solution :</u>

v = ω × R

v = ( θ / Δt ) × R

v = ( 10 × 2π / 30 ) × 4

v = (8π / 3) m/s

<h2>v ≈ 8.4 m/s</h2>

Answer:

8.4 m/s

Explanation:

The toy completes 10 circle in 30 seconds. So its frequency of revolution is

f=\frac{10}{30 s}=0.33 Hz

The periof of revolution is the reciprocal of the frequency, so

T=\frac{1}{f}=\frac{1}{0.33 Hz}=3 s

The radius of the circular path is

r = 4.0 m

So the total distance covered by the toy in one circle is the length of the circumference:

2\pi r

And so the average speed is

v=\frac{2\pi r}{T}=\frac{2\pi (4.0 m)}{3 s}=8.4 m/s
