Question 16
2.9 Three Pulleys
2.9a A thin, light rope is draped over three frictionless pulleys arranged around the origin as shown. Each pulley is a solid disk of radius r=2cm and is equidistant from the origin. 5kg mass is attached to one side and a 7kg mass to the other.
Before the masses are released and in motion, what is the total angular momentum in kgm2/s around the origin?
Question 17
2.9b What fraction of the angular momentum is in the pulleys?
