With what maximum speed can an unsecured passenger stay in their seat on a Ferris wheel that has a diameter of 12 m.

Question

so, this happens when Fn is zero or mg = mv^2/r.
v = sqrt(gr)

so is it v=sqrt9.8
what would happen with the 12m

Answer 1

12m is the radius r
solving for v gives you
sqrt(g * r)
