Question

A jet flies at constant altitude with speed 720 km/h while banking at the angle shown. If the circular-turn radius is R km, find √R.

G1 Physics · Accepted Answer

For level flight while banking, tanθ=v²/(Rg). Using the banking angle shown and v=720 km/h=200 m/s gives R=16 km. Therefore √R=4.
