    Mass being dropped on spinning disk problem NEED HELP!!

    1. A disk has a radius of 1.25m and a mass of 10kg. It lies flat on a smooth table and is spinning with an initial velocity of 10 rad/s about a pin at its center. A 5kg mass is dropped on it at a distance of 0.50m from its center. Find:
    (Extra credit) if the coefficient of kinetic friction between the block and the disk is 0.40, determine:
    i. the time while slipping























    ii. the distance traveled while slipping
    1. The problem statement, all variables and given/known data



    2. Relevant equations
