Speed of the aircraft,

v = 720 km / h = 720 \times 5/18 = 200 m / s

Acceleration due to gravity,

g = 10 m / s^{2}

Angle of banking =

1 5^{o}

For radius,

r

, of the loop, we have the relation:

N cos θ = m g

N s in θ = \frac{m u ^{2}}{R}

t an θ = u^{2} / R g

r = u^{2} / g t an

θ

= 20 0^{2}

/ (

10 t an 1 5^{o}

)

= 4000/0.26

= 14.92 km
