A solid non-uniform disk of mass M and radius R rolls without slipping down an incline that makes and angle of θ with the horizontal. It is released from rest and travels a distance d in time t . Write an expression for the moment of inertia of the disk. Your answer will be in terms of d, M, R, t, θ and g. The mass distribution of the disk is not uniform, so do not simply use I=1/2MR^2, which is the formula for a uniform disk.
