Homework Equations
The Attempt at a Solution
The friction is not mentioned anywhere, so let's forget about it, i thought that it has something to do with the normal force, so it should be like this:
Nmax + mg = mv^2/r
does it need some advanced stuff about the normal force to solve this?
does it have something to do with friction between the passenger and the seat ?
Thanks for clearing this up for me, and sorry for my poor English.
