Homework Statement
The flying disc except rotation moves up and down. Show that such movement will be suppressed by frictional force of air, which has a force momentum relative to the center of disc ##N=-K\omega##. What is the time profile of this process?
Homework Equations
##L= T - V##
##T=Tradial + Trot + Tupdown##, ##V=0##
The Attempt at a Solution
I haven't seen such type of problem before. So I don't know if I should construct lagrangian and generally don't have idea how connect frictional force with this movement. Probably small kick should help and probably than I will able to solve it.
Please give me some kick :) Thank you.
