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?
At what temperature would water boil if the outside pressure was only 19,900 Pa in degrees Celsius?
