3) A solid cylinder of radius R and mass M rolls on an incline at angle o. The cylinder is released with its centre of mass at a height h. a) What is minimum coefficient of static friction so that the cylinder will roll without slip- ping? b) What is the speed of the centre of mass of the cylinder after its centre of mass falls a vertical distance of h/2? c) Suppose that the static coefficient is smaller than its minimum value so that the cylinder does not roll but begins to slip. Find the the speed of the centre of mass of the cylinder after its centre of mass falls a distance of h/2. Let the coefficient of kinetic friction be /k and assume that Ax
