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 ?

Text Solution

Verified by Experts

Here `0=15^(@)`
`v=720km//h=(720xx1000)/(60xx60)=200 "ms"^(-1)`
`g=9.8ms^(-2),"from"tantheta=(v^(2))/(rg)`
`v^(2)="r g"tantheta`
`thereforer=(v^(2))/("g"tantheta)=((200)^(2))/(9.8xxtan15^(@))` ltbrrgt = 15232m = 15.232 k.m
