A 80kg person at the fair rides the famous "spinning bottomlesscylinder", (r = 4m). When the cylinder spins fast enough the floordrops away but you dont fall because of friction (fs= 0.45)

a) what is the minimal velocity the cylinder must spin so you dontfall?

b) what is the minimum centripetal force needed?
