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