A plane flying at 500 km / h on the level is making making a circular turn with radius 5 . 0 km. The lift force on a plane is PERPENDICULAR to the wings. The gravity force points down as always. What angle is does the plane have to bank at (i.e., at what angle to the horizontal must its wings be tilted) to make the turn? HINT: This is really just the road banking problem all over again. Solve for the banking angle using Newtons 2nd law. Draw the free body diagram. a) 2 . 1 . b) 4 . 1 . c) 10 . 2 . d) 17 . 4 . e) 21 . 5 .
