Physics

A plane flies horizontally at constant ground speed v=720km/h. The pilot is informed by an air traffic controller that he must immediately change his direction of flight while keeping the same altitude. The pilot performs a turning maneuver by rolling the plane to a banked position. Then she increases the airspeed in Δv to keep the plane at constant altitude. As a result, the plane describes an arc of radius R=8km. Find the increase in airspeed Δv in km/h. Assume that the lift force is proportional to the square of the speed and that it is always perpendicular to the plane of the wings.

  1. i know we're u got the question,I will tell the answer,if u tell me the answer to the helium question,

    we should trade

  2. it's about use the Ek = Ep

    and V is using the root mean square velocity

  9. If it was going straight,it's weight would equal the lift force,since it is banked at an angle,the force will be split into components,

    horizontal lift force equals Lsin=mv^2/r,the centripetal force hence describing a radius,

    vertical component must equal the weight,lcostheta=mg,

    then it is done,and please if u have done the lattice point question tell me,
