1. The problem statement, all variables and given/known data A particle of mass M is released from rest at the top of a frictionless slide that is h distance from the ground. The lowest section of the slide is part of a circle with radius R. The setup looks like a candy cane. At its lowest point (bottom of circle) what is the normal force acting on the particle? 2. Relevant equations F = ma N = mg These seem to be relevant...but I'm not sure. KE = (05)Iw2 PE = mgh L = Iw I(particle) = mr2 T(net) = Ia 3. The attempt at a solution KEi = (.5)m(0)^2 = 0 KEf = (.5)mvf2 + I(v2/r2) By conservation of Energy KEf = KEi but this doesn't tell me anything about the forces on the particle. If the particle is at the bottom then I don't see why N will be equal to other than just mg.
