Homework Statement
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?
Homework 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
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.
