1 Two Objects were connected on a rough incline of 30 degrees via a pulley having a radius of 0.3m and moment of inertia of 7 kg-m-m. The 5kg on the incline experienced a coefficient of kinetic friction pf=0.25. The vertical hanging mass was 33.5 kg. (show work) The vertical portion of the string was cut after 4 seconds 1. Find the new acceleration a2 of the 5-kg object 2. Find the distance d2 moved by the 5-kg after 3 seconds with the new acceleration a2 3. Find the extra rotation in degrees of the pulley when the 5-kg moved the extra d2 meters in 3 seconds
