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.

    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

  • Physics -

    it's about use the Ek = Ep

    and V is using the root mean square velocity

  • Physics -

    no,I swear I will tell,for the helium answer

  • Physics -

    it's about 95.5

    Hey what's the answer to this question ?

  • Physics -

    as promised,56.4,we should help each other out,send me ur email

  • Physics -

    btw,have u done the lattice point question,please tell

  • Physics -

    how you solve that

  • Physics -

    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,
