2. (20 pts) The cylinder shown in the figure has a mass of 6 kg. It is attached to a cord which is wrapped around the periphery of a 20-kg disk that has a moment of inertia Ix -0.40 kg-m². The cylinder is initial moving downward with a speed of 2 m/s. Neglect the mass of the cord in the calculation. a) Setup angular momentum and impulse equation for the disk and linear momentum and impulse the cylinder. b) Determine the tension force (T) on the cord and the velocity the cylinder (va) after 2 s. (hint: y- can use equations from a) or other methods) 0.2 m W VB = 2 m/s M-6kg Mo-20kg IA-040 kg m √v=2m/s
