The 30-kg disk is originally spinning at ω = 125 rad/s. If it is placed on the ground, for which the coefficient of kinetic friction is μ_C = 0.5, determine the time required for the motion to stop. What are the horizontal and vertical components of force which the member AB exerts on the pin at A during this time? Neglect the mass of AB.
