An aircraft executes a horizontal loop at a speed of 720 km/h with its wings banked at 15°. What is the radius of the loop?
Answer & explanation
Correct answer: option 2
The angle of tilt of the aircraft is given by,
tanθ= v2/rg
Here, θ is the angle of tilt of the aircraft, r is the radius of the loop, v is the loop speed and g is the acceleration due to gravity.
Substitute the values in the above equation.
\(r = \frac{720 \text{km/h}\frac{1}{3600} \text{s}}{10 \text{m} \frac{1}{1000} \text{km}} \) ≈ 15 Km
Thus, the radius of the loop is 15 km.
