An aircraft executes a horizontal loop at a speed of `720 km h^(-1)` , with its wings banked at `15^(@)` What is the radiue of the loop ?

Explanation

Here `theta = 15^(@) `
` upsilon = 720 km// h = (720 xx 1000)/(60 xx 60) = 200 m s^(-1) , g = 9 .8 ms^(-2) `
from tan ` theta = (upsilon^(2))/(r g ) `
` r = (upsilon^(2))/(g tan theta )= (200)^(2)/(9 .8 xx tan 15^(@)) = 15232 m = 15.232 km ` .
