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?arrow_forward
